The program includes a powerful mesh generator and routines (contour lines, 3D graphics, etc.) for comfortable evaluation of the modelling results.Data input is in accordance with conventional WINDOWS operations and can therefore be learned almost entirely without the use of a manual. Graphic output supports the true-type fonts supplied with WINDOWS, so that an excellent layout is guaranteed. Colour output and Bitmap graphics are supported. DXF files can also be imported by means of the integrated Mini-CAD module (see the Mini-CAD manual).It is not the aim of this manual to give an introduction to finite element methods. For details offinite element methods you are referred to O. C. Zienkiewicz, The Finite Element Method, pub-lished by McGraw-Hill. The hydraulic principles upon which the FEM program is based may be taken from, e.g., Buss, “Unterströmung von Deichen” (Percolation Below the Base of Embank-ments) (Mitteilungsheft 92, Leichtweiß-Institut, TU Braunschweig – Announcements of theLeichtweiß Institute, No. 92, Technical University of Braunschweig). The program has been used in a large number of projects and has been thoroughly tested (using analytical solutions and incomparison with other FEM applications). No faults have been found. Nevertheless, liability for completeness and correctness of the program and the manual, and for any damage resulting from incompleteness or incorrectness, cannot be accepted.2 Installation and language selectionFor installation and subsequent registration of GGU software, please refer to the information inthe “Installation notes for GGU Software”, which are supplied the program.GGU-SS FLOW3D (International version) is a bilingual program. You may choose to work inGerman or English. The international version is delivered with English as the default menu and graphics language.If you would like to work with GGU-SS FLOW3D (International version) in German, start theprogram and go to “File / New” in the initial menu bar. An expanded menu bar appears. Go to the “?” menu and there to the menu item “International version” and deactivate the switch for translat-ing the menus and graphics (see also Section 7.12.6).3 Starting the programAfter starting the program you will see two menus at the top of the GGU-SS FLOW3D window: • File• ?After clicking on the “File” menu, a previously analysed system can be loaded by means of the“Load” menu item, or a new one created using “New”. After selecting the system, the menu bar will show eleven menus:• File• Mesh(x/y)• z• I mesh• Boundary• System• Graphic preferences• Page size and margins• Evaluation• 3D• ?After clicking one of these menus, the so-called menu items roll down, allowing you access to all program functions.The program works on the principle of “What you see is what you get”. This means that the screen presentation represents, overall, what you will see on your printer. In the last consequence, thiswould mean that the screen presentation would have to be refreshed after every alteration youmake. For reasons of efficiency, and as this can take several seconds for complex screen contents, the GGU-SS FLOW3D screen is not refreshed after every alteration. If you would like to refresh the screen contents, press either [F2] or [Esc]. [Esc] will additionally set the screen presentation to A3 format.4 Program conceptThe program uses the finite element method. The real solution is a linear approximation for each element. Triangular prisms are used as finite elements. To simplify data input, the mesh is initially generated in plan. The projection of the triangular prisms onto the plan surface results in triangles, so you must first generate a triangular mesh. Depending on the complexity of the system, a num-ber of height ordinates are associated with each node of this basic mesh, which describe the sys-tem in the third dimension. The height ordinates can possess different values at each node. Theonly condition is that every node has the same number of height ordinates. This allows complex systems to be generated.Using this type of mesh generation, successive planes of nodes are located above each other,whereby “plane” can be somewhat misleading because the nodes of a “node plane” are not neces-sarily on one plane. Instead of the term “node plane” we will simply use “plane”.The regions between these planes are called “layers”. They are filled with triangular prisms.Figure 1 Planes and layersYou can assign a boundary condition to each node (source or potential). You can also assign dif-ferent soil properties to each triangular prism.If you have already worked with the GGU program GGU-SS FLOW2D (formerly GW2), you will hardly encounter problems with the GGU-SS FLOW3D mesh generator. The additional effortinvolved consists of having to manage a “battery” of z ordinates for each node.5 Short descriptionSince I know from personal experience that reading user-manuals is quite a chore, there will now follow a short description of the main program functions. After studying this section, you will be in a position to model steady-state groundwater flow. More detailed information about theprogram can be obtained from the subsequent chapters as you require it.• Design the system to be modelled.• Start GGU-SS FLOW3D and go to “File / New”. Enter the number of element layers. This can be increased or decreased later.• If necessary, adjust the sheet coordinates to fit your system. Use “Page size and margins / By hand” to do this.• Then go to “Mesh(x/y) / Define nodes”.• Using the mouse, click the governing nodes (points) in your system. The points will be numbered. Alternatively, you can also enter the nodes in tabular form using “Mesh(x/y) / Change”. Each newly generated node is awarded the values entered in “z / Standarddepths” as z ordinates. During and after mesh generation, you can edit the z ordinates asso-ciated with a node at will (see below).• If the nodes lie outside of the visible sheet coordinates, go to “Page / Auto-resize” or press [F9].• Now go to “Mesh(x/y) / Mesh “by hand”” and unite groups of three nodes to single trian-gular elements. In this manner you generate a rough structure for your system. Alterna-tively, by using “Mesh(x/y) / Automatic”, you can have the program do this work auto-matically for you. During automatic mesh generation the triangular prisms are assigned the standard soil column for all new triangular elements. The standard soil column defines the soil numbers of the individual triangular prisms. The soil numbers can also be subsequently edited at any time.• If you want to edit the positions of mesh nodes, select one of the menu items “Mesh(x/y) / Edit”, “Mesh(x/y) / Change” or “Mesh(x/y) / Move”.• To define the depths of the planes, enter the plane surfaces in the “z / Standard depths”menu item.• If you want to delete a triangular element, select the “Mesh(x/y) / Mesh “by hand”” menu item once again and click the three corner nodes of the corresponding element. After select-ing this menu item, try a double-click in a triangular element.• You can refresh the screen at any time using [ESC] or [F2].• Turn your rough structure into a fine structure by using the menu items “Mesh(x/y) / Indi-vidually refine” or“Mesh(x/y) / Section” or “Mesh(x/y) / All”.• After mesh refinement, you can still edit your system at will using “Mesh(x/y) / Define nodes”, “Mesh(x/y) / Mesh “by hand””, etc.• For demonstration purposes, use the menu item “Mesh(x/y) / Move” to generate one or more acute, and thus numerically unfavourable, triangular elements. Then select the“Mesh(x/y) / Optimise” menu item and follow the effects on the screen.• Previously, each node was assigned the standard depths during mesh generation. If you want to see your mesh in a vertical section, use “z / Define section” to define a section through the system.• Use “Boundary / Individual potentials”, for example, to define the boundary conditions governing your system. A potential can be assigned to the node in the current plane or to all nodes associated with this point.• You can move through the planes using the and tools, which you can find in the toolbar at the lower left of the program window. The plane and layer in which you now find yourself are shown in a separate legend.• If you wish, you can edit the soil number using the “Boundary / Individual soils” or “Boundary / In section” menu items. Every soil number can subsequently be assigned dif-ferent soil properties. The soil numbers defined refer to the current layer.• If necessary, edit the soil properties using the menu item “System / Soil properties”.• Once you have completed mesh generation, go to “System / Run” to commence modelling.Where required, a bandwidth optimisation will be carried out before modelling com-mences, in order to achieve a numerically favourable equation system.• If wished for, you can send the results to a printer as an output table or write them to a file once modelling is finished. However, this method of result presentation is generally less than satisfactory to the client.• So, proceed immediately to the “Evaluation” or “3D” menus. You can almost always leave the subsequent dialogue boxes using the “OK” button, without having to make furtherchanges. The program will usually suggest sensible input. The “Determine extreme val-ues” switch, which appears in a number of dialogue boxes, should be clicked once how-ever, otherwise an error message will appear.• Define a section (menu item “z / Define section”) and then press Return. Now select thetool from the toolbar at the lower left of the program window. You will now see a “cut-away” of the system. You may rotate the system in steps around the z axis using thetool. Try pressing the F9 function key (or use “Page size and margins / Auto-resize”).Change the current plane from the one you are now in.• If you find yourself in a section and wish to return to a representation or evaluation in plan, go to “Mesh(x/y) / Mesh”.• If you have a colour printer correctly installed in WINDOWS, you can create colour output by going to “File / Print and export” and then pressing the “Printer” button in the subse-quent dialogue box. For black and white printers, grey scales will be used.• At the end of this manual, the program is described using a comprehensive example.This short description demonstrates that only a few items need be selected to model a groundwater system. All further menu items deal principally with saving data, layout and further evaluation of the model, where required. The description will ensue in the following chapters.6 Theoretical principles6.1 OverviewAn analytical solution can be given for simple groundwater systems. When modelling complexsystems, we must rely on numerical methods of solution. In principle,• finite difference methods (FDM) and• finite element methods (FEM)are employed. To facilitate this, the whole area is subdivided into numerous small (finite) sub-areas (elements). When employing FEM, triangles are generally used to represent these sub-areas.Within the triangles, simple, generally linear, approximation functions are applied. The real, com-plex total solution is composed, mosaic-like, of the numerous simple partial solutions. This gives rise to equation systems, the number of unknowns of which correspond to the number of system nodes. Using the finite difference method, we normally only have the option of discretising thetotal area by means of rectangular sub-areas. In contrast to FEM therefore, FDM is substantially less flexible with regard to adjustment to complex boundary structures. Mesh refinement is also less simple to perform in certain areas. In addition, the equation systems which result for FEM are numerically more stable. The principle advantage of FDM consists merely of the theoretically less complex underlying mathematical relationships, which will generally be less interesting to theprogram user. GGU-SS FLOW3D makes use of the finite element method.When using this program, please remember that all finite element or finite difference procedures are approximation methods. The quality of the approximation compared to the real solution in-creases with the fineness of the mesh. You should take care that the mesh is tighter in those areas where the principal subsurface hydraulic activity takes place (e.g. wells, seepage elements). The shape of the triangles also exercises a certain influence. The optimum conditions are provided by isosceles triangles. You can get an idea of the quality of the solution by modelling the same sys-tem again, but using a either a finer or a coarser mesh and comparing the results of the two model-s.The following further general remarks are important:• Triangular elements are used.• Darcy’s Law applies.• The piezometric heads are computed linearly for each element.• A constant approximation of velocities for each element results from the linear approxima-tion of the piezometric heads. In order to improve the quality of the velocity approxima-tion, the velocities for computation of flow lines are converted to mean node values in afollow-up computation.The procedure is:The velocities from the neighbouring elements are added for each element node and thendivided by the number of neighbouring elements. This allows an improved representationof velocity. By the nature of things, the results at the boundary nodes are not as exact.Moreover, the approximation quality of velocities in the region of element nodes belongingto elements of varying material types can deteriorate. If the velocities in such “boundarynodes” are of great interest, some assistance can be had by refining the element mesh inthese regions.6.2 Differential equationThe application solves the differential equation:k r ∗ k x∗∂2h/∂x2 + k r ∗ k y∗∂2h/∂y2 + k r ∗ k z∗∂2h/∂z2 + Q = 0 Where• k x, k y, k z= permeability in m/s, for example, for the x, y and z directions• h= piezometric head in m, for example• k r= coefficient for determining the permeability in the unsaturated zone(dimensionless)• Q= discharge in m³/s, for example• x, y, z= coordinates in m, for exampleThe parameter k r takes account of the change in permeability in the unsaturated zone r above the groundwater table and assumes values between 0.0 and 1.0. In the saturated zone, k r is equal to1.0. The parameter k r is a function of the porewater pressure u. The porewater pressure u is calcu-lated from the piezometric head h, the elevation head y and the unit weight of water γw.u = (h - z) ∗γwThe curves corresponding to three typical soils are shown in Figure 2. The inclusion of this pa-rameter in the differential equation offers the significant advantage, among others, that phreatic lines can be very simply computed during the ensuing finite element analysis.Figure 2 k r = f(u)Further explanation is provided by Figure 3. In the case of a horizontal groundwater table, all four parameters h, y, u and k r are given as a function.Figure 3 Unsaturated zoneIf unsaturated zones are present in the system and computation of the phreatic line is needed, this will require an iteration process, as the location of the phreatic line is not known from the outset.In the first iteration step, the program initially assumes that all system regions are saturatedk r = 1.0After the initial computation of the piezometric heads at the system nodes, the porewater pressures u are computed and k r determined. Using the thus modified permeabilities, the system is remod-elled with new piezometric heads and correspondingly new porewater pressures and k r values. The iteration process is continued until the difference in piezometric heads in iteration step (i) and (i -1) fall below the user-defined limit value (iteration deviation).Remark on boundary conditions:The case of an impermeable boundary is considered automatically by the finite element method.All system boundaries that do not posses water level or source boundary conditions are automati-cally impermeable.7 Explanation of the individual menus and items7.1 OverviewA few of the program functions cannot be reached by means of the menu items. These programfunctions can only be activated via the toolbar in the lower left program window.If you click the corresponding tool in the toolbar with the left mouse button and keep it pressed, the program functions “hidden” behind these icons are shown in the bar at the bottom of the pro-gram window. Of particular importance are the iconsand and ,with which you can move from one plane to the next. This is important when defining soil num-bers, z ordinates and when evaluating modelling results for example.In this chapter, the individual menus and their associated menu items will be explained.7.2 File menu7.2.1 “New” menu itemAfter selecting “New”, the number of element layers must be specified in the dialogue box.Element layer numbering begins at the bottom with “1”, the planes bounding an element layer are also numbering continuously from bottom to top. The number of element layers is – because the system ends at the base – one less than that of the planes; see the schematic section below.Figure 4 Planes and layers7.2.2 “Load” menu itemIf you have entered data at a previous “session” at the computer, and saved these as described in the “Save” menu item, you can reload them by selecting this menu item. It is then possible to edit the data according to your wishes.7.2.3 “Save” and “Save as” menu itemsYou can save data entered during program use to a file, in order to have them available at a later date, or to archive them. For reasons of transparency, it makes sense to use “.F3D” as the fileextension, as the file requester box for the “Load” menu item only shows files with this extension.If you do not enter an extension when saving, “.F3D” will be used automatically. If the currentsystem has been modelled, the results can be saved to a dataset. If this file is later reloaded, theresults remain available for evaluation without renewed computation.7.2.4 “Read ASCII file” menu itemIf the coordinates of FEM mesh nodes are available as an ASCII file, this data can be read into the program. The data must consist of rows containing the x value and the y value of each node. Deci-mal fractions must have a point and not a comma. When loading the ASCII file, you only need to specify in which columns the x and y values are located. New x and y coordinates are assigned the standard depths.The current line of the ASCII file is shown at the top. You can move through the file using thearrow buttons on the right. If all the information is correct, the result for the row is shown in the box below each column. Otherwise, “Error” appears. You may need to change the column delim-iter. If the file contains invalid as well as valid rows, these will simply be skipped during reading.Finally, select the “Read data” button. You can then process the coordinates to a new FEM mesh.7.2.5 “Save ASCII file” menu itemIf a FEM mesh has been generated, the node coordinates can be saved in an ASCII file. The x and y coordinates of the underlying mesh (2D) are saved and, in addition, if the system has been mod-elled, the potential of the current plane.7.2.6 “Print output table” menu itemYou can print an output table. The results can be sent to the printer or to a file (e.g. for further editing in a word processor). The output contains all analysis information, including the system data. First decide the extent of output,by activating the corresponding switches.You can then define more output preferences. Using the “Edit” button, the current printer prefer-ences can be changed or a different printer selected. Using the “Save” button, all preferences from this dialogue box can be saved to a file in order to have them available for a later session. If you select “GW3.DRK” as file name and save the file in the program folder (default), the file will be automatically loaded next time you start the program. Using the “Page format” button you candefine, among other things, the size of the left margin and the number of lines per page. The“Head/foot” button allows you to enter a header and footer text for each page. If the “#” symbol appears within the text, the current page number will be entered during printing (e.g. “Page #”). If you do not wish pagination to begin with “1” you can add an “offset” number to the check box.This offset will be added to the current page number. The text size is given in “pts”. Using thebuttons at the bottom of the dialogue box you start output to the “Printer” or to a “File”, the name of which must be subsequently entered. If you select the “Window” button the results are sent to a separate window. Text editing options are available in this window, as well as loading, saving and printing.7.2.7 “Printer preferences” menu itemYou can edit printer preferences (e.g. swap between portrait and landscape) or change the printer in accordance with WINDOWS conventions.7.2.8 “Print and export” menu itemThe following dialogue box appears:• “Printer”allows graphic output of the current screen contents to the WINDOWS standard printer orto any other printer selected using the menu item “Printer preferences”. For direct output(printer), the following dialogue box appears:。

Changing fixed host IDs during your license term may incur a re-licensing fee. Re-licensing fees are not necessary (maximum one year) when users utilize a USB or parallel port hardware key (dongle) as their host ID. To move the dongle (and hence license server) to a different computer, the user simply needs to change the first line in their license file to reflect the computer name change. For example, if the license server was previously running on a server named Celsius and you wish to move it to Kelvin, you would change the first line in the license file from:SERVER Celsius FLEXID= “your ID”toSERVER Kelvin FLEXID= “your ID”Installations1.2.3 NewWindows Vista/XP InstallationsNote: You must have Administrator privileges to install FLOW-3D under Windows XP/Vista. Before installing FLOW-3D, you should close all other programs that might be running on your computer.Step One—The installation of FLOW-3D on a computer running Windows is a relatively automated process. If Autorun is enabled on your CD-ROM drive, the installation should begin when the CD is inserted. If Autorun is not enabled or if, for some reason, the installation process does not begin on its own, simply run the setup.exe program in the root directory of the CD. This can be done by either running it from the Run command under the Start button or by double-clicking on setup.exe in Windows Explorer. Once you have started setup.exe, you will see the Preparing to Install dialog displayed on the screen. This dialog requires no user input and will be gone after several seconds.Step Two—The next dialog you will see is the Welcome dialog. Click Next to move to the next step.Step Three—The next dialog is the FLOW-3D License Agreement. Please read it carefully. If you agree to all the terms, click the Next button to signify your agreement and move to the next dialog.Step Four—The next dialog is the User Information dialog Enter your name and the company name here, and then click Next to move to the next step.Step Five—On the next dialog, choose a destination location for FLOW-3D on your computer. The default location for FLOW-3D is c:\flow3d\”version” where “version” represents the version being installed.If a license server is currently running in the selected installation directory, a dialog will appear which will assist you in terminating this license server easily. If the license server is not terminated, a reboot will be required to complete the installation.Step Six—The Choose an Installation Option dialog box appears next:1.2 INSTALLATIONDetailed information on new installations of FLOW-3D is given below in New Installations. Help with upgrade installations for FLOW-3D is given below in Upgrade Installations. Instructions for installing a new or replacement license file is contained in Installing a New/Replacement License File.1.2.1 General Licensing MattersLicense Technology and TermsFLOW-3D uses the licensing package FLEX lm,by Acresso Software. FLEX lm enables FLOW-3D licenses to be shared across a network. More information about FLEX lm and its tools can be found below under FLEX lm License Administration Tools. A FLEX lm end-user manual is available in the “utilities” subdirectory of the installation. Flow Science will provide you with a FLOW-3D license file, named flow3d.lic.License Files and ServersA valid license file from Flow Science is required to use FLOW-3D. This license file will be sent to you as an email attachment from licenses@, Flow Science’s License Administrator. As described in later portions of these instructions, this license file must be saved in a FLOW-3D directory on a computer you choose to be your "license server."FLOW-3D can be used on multiple computers on your network. However, one computer must be selected to be the license server. If the computer you choose to be the license server will not actually be used to run FLOW-3D, then only the FLEX lm license server needs to be installed on it.If you plan to install the FLEX lm license server on a Windows computer, a dongle that attaches to the parallel or USB port of your computer will be provided by Flow Science. This key should have been enclosed in your FLOW-3D package.TokensThe total number of FLOW-3D solver processes that you can run concurrently is determined by the number of "tokens" contained in your license file. The number of tokens available depends on how many were purchased. The license server checks tokens out to client computers on your network, and then checks them back in when the application has completed. In this process, tokens are counted by the license server and when the total number of tokens that you have purchased has been reached, no more tokens can be checked out until a used token is checked back in.There are essentially an unlimited number of tokens available to run FLOW-3D’s auxiliary programs such as the preprocessor, the postprocessor, and the various visualization options.There are several different types of solver tokens. The most important distinction is between "serial" solver tokens and "parallel" solver tokens. Flow Science offers multi-processor versions of FLOW-3D for both shared-memory (SMP) and distributed-memory (cluster) environments. A shared memory parallel solver token (shown in your license file as “hydr3dp”) enables you to run FLOW-3D simulations using more than one processor on a multiprocessor computer. For the distributed-memory version (FLOW-3D/MP), a hydr3d or hydr3dp instance token is required as well as hydr3dmpi rank tokens. For example, to run a simulation on 16 processors using FLOW-3D/MP, the license file must have a hydr3d or hydr3dp token and 15 hydr3dmpi tokens.Unless you have purchased tokens for one of the multi-processor versions, your license file will contain one or more serial solver tokens (“hydr3d”). These serial solver tokens can be used on either single-processor or multiple-processor computers running any supported operating system.Definition of Client and License ServerAny computer running FLOW-3D is referred to as a “client.” The computer on which the FLEX lm license server is installed will be referred to as the “license server.” A computer that runs both FLOW-3D and the license server is called a “client/server.”“Software Package” and “Software Distribution”The terms “software package” and “software distribution” will be used to refer to the directory structure containing all of the data files and executables needed to run FLOW-3D on a particular computer. Floating vs. Node-Locked LicensesThere are two general types of licenses used to enable FLOW-3D: "floating" and "node-locked." A floating license is the most common type of license and is available to any computer on your network. You can also ask for your license to be a node-locked license. Node-locked licenses can only be used on the designated computer.Both floating and node-locked licensing schemes require that one computer be designated as the license server.Floating LicensesTo utilize floating licenses, it is important that both the computer you intend to use as your license server and your network are reliable. The TCP/IP protocol must be loaded and functional, and all intended clients must be able to access the license server. Floating licenses may also be accessed through a VPN tunnel.The computer that is acting as your license server may be any computer on your network, and that computer does not need to have FLOW-3D installed on it. The license server may be a Windows or a Linux computer.. You may load FLOW-3D on any client with a supported Linux or Windows computer on your network. A hardware key is not needed on a client computer unless it utilizes a node-locked license.Running FLOW-3D on a stand-alone computerTo employ a floating license on a single computer, select the client/server option.Running FLOW-3D over a networkThe license server and the clients may reside on the same local area network, over a WAN, or across VPN. FLOW-3D must be installed on each locally on each client.Node-Locked LicensesUsers may choose to have their solver tokens locked to a particular computer so that only that computer can run the solver.Advantages and DisadvantagesBoth floating and node-locked licensing schemes have their advantages and disadvantages. A floating license is advised if several people are sharing a license, or if you want to be able to run FLOW-3D on a different computer if a particular computer is busy. With a floating license, you can also setup a problem on one computer while using another to run the FLOW-3D solver on a second problem. Of course, if others are using all available tokens, the solver won't run until a token becomes available. The main advantage of a node-locked license is the ability to insure that your token(s) are always available to you and not available to others on your network.Note: All licenses are floating licenses unless specifically requested as node-locked.FLEX lm License Administration ToolsAcresso Software provides utilities for you (or your license administrator) to help manage FLEX lm licensing activities.A FLEX lm End User Manual is available in the "utilities" subdirectory of the distribution. This manual is available in both PDF and HTML format. The PDF file can be read using Adobe Acrobat. For Windows computers, a program (lmtools.exe) is provided with all installations. With LMTOOLS, you can start, stop and configure FLEX lm license servers, get system information, get server information, and more. For more information, see Section 7.16 of FLEX lm End User Manual.On Windows computers, the license manager daemon (lmgrd) will restart automatically whenever the computer is rebooted. On Linux computers, however, you will have to start the license manager each time the computer is rebooted. To have the license manager start automatically on Linux requires editing the appropriate boot script and inserting the appropriate startup commands. See Section 6.2 of the FLEX lm End User Manual for more information.A summary of commonly used administration tools on Linux is included here. Full descriptions of these and other available utilities can be found in Chapter 7 of the FLEX lm manual.lmdiag – diagnoses license checkout problems.(Useful debugging command: lmutil lmdiag –n –c full_license_file_path )lmdown – gracefully shuts down all license daemons on the license server node.lmgrd – the main daemon program for FLEX lm.lmhostid – reports the hostid of a system.lmreread – causes the license daemon to reread the license file and start any new vendor daemons.lmstat – helps you monitor the status of all network licensing activities.(Useful debugging command: lmutil lmstat -a -c full_license_file_path )lmver – reports the FLEX lm version of a library or binary file.Note: It is not recommended to use "kill –9" to shut down the license server on Linux computers.Either use "lmdown" or use the "kill" command without the "-9" parameter.Option 1—"Client/Server" -- Choose the first option if you intend to run FLOW-3D on this computer and you want this computer to control your FLOW-3D licenses (that is, act as the license server) for use on other computers across a network. This situation is reflected below:Be sure to copy your FLOW-3D license file (flow3d.lic) to your “licenses” directory once installation is complete. Your computer will be acting as a license server, and can issue tokens to any FLOW-3D clients on the network.Note: Choose the server for your FLOW-3D environment carefully. The license server requires a stable computer. Moving the FLOW-3D license to a new computer before your license period expires may entail a re-licensing fee.Option 2—“Client (FLOW-3D)” -- Choose this option if you intend to only run FLOW-3D on your computer, and the computer is not going be used as the license server(i.e., this computer is a client only and another computer is the license server). Be sure to copy the license file from the server to your licenses directory and also make sure the server name for your license server computer is listed in your FLOW-3D license file.No FLEXlm license server components are installed.Option 3—“Server (license server)”—Choose Option 3 if you wish to have your computer function only as a license server and you do not intend to run FLOW-3D simulations on it. This choice will only install the FLEX lm server on your computer. FLOW-3D itself will not be installed, and thus cannot be run on this computer.After making your selection in the Choose an Installation Option dialog box, click OK to move on. Step Seven—If you chose Option 1 or 3 in Step Six, a dialog will appear asking you to choose the type of key to which your license will be locked. The most common key type is a USB key and looks very similar to a USB memory stick. If you have a parallel port key (Windows only), choose that option. If your license will be locked to your Ethernet address (uncommon), then choose this option. If you are not sure what your license will be locked to, select the last option, “Don’t know.” All possible drivers will be installed. Select Next to continue.At this point, the installation displays the following screen which will assist you in shutting down currently running FLOW-3D license servers.Step Eight—At this point, installation of FLOW-3D and all required drivers is ready to begin. Click Install to complete the installation.Step Nine—At this point, FLOW-3D should be installed and the final step is to install your license file. If you have already received your license file, simply copy it to the "licenses" directory and proceed to Step Eleven to start your license server. If you have not received your license file, follow the instructions in Step Ten to obtain a license file.Step Ten—In order to issue a license file, Flow Science needs both the host name and the host ID of your server. To obtain this information from your server, double-click on the lmtools.exe program file in the licenses subdirectory under the FLOW-3D installation directory and select the System Settings tab. If using a hardware key, provide the FLEXID and the Computer/Hostname to Flow Science. If you are not using a hardware key, provide Flow Science the Ethernet address and the Computer/Hostname.Once your Hostname and Ethernet or FLEXID have been received, the License Administrator at Flow Science will send you a license file ("flow3d.lic"), which will come in the form of an attachment to an email. It is an ASCII file with encryption codes that allow it to be used for only one Host_ID. Check the license file to be sure that it contains the Hostname and Host_ID that matches your license server. Now copy the attachment to the "licenses" folder in your FLOW-3D installation directory.Step Eleven—Start the license server (Client/Server and Server installations only). In LMTOOLS, click on the Start/Stop/Reread tab to display the Start Server, Stop Server, and ReRead License File buttons. Click on the Start Server button to start the license server. If the message in the lower left corner reads, “Server Started” then the server successfully started. If it reads, “Server Start Failed,” select the Stop Server button and then select the Start Server button again. You should see the message, “Server started.” If not, contact Flow Science, Inc., at support@ or 505-982-0088.If you chose Option 1 or 3 in Step Six of New Computer Installations, then, in order to ensure that the license server will be started each time you reboot your computer, you should go to the Config Services tab and make sure that the Start Server at Powerup and Use Services boxes are checked.At this point, you should be ready to run FLOW-3D.Linux InstallationsInstallation OverviewTo install the FLOW-3D software package on a Linux computer, you will need to accomplish the following: •Install FLOW-3D from the CD-ROM onto your hard disk using the “install” program or an alternate way is to use the “install_flow3d” script;•Copy your license file into the "licenses" subdirectory and start the license server (if it is not already running);•Execute the flow3d.sh (or flow3d.csh for c-shells) script to set the required environment variables.Step-by-Step ProcedureStep One—Insert the distribution CD into your CD drive.Step Two—Open a command prompt and set the current working directory to the CD mount directory and then to the "unix" subdirectory. For example, if the mount directory is "/cdrom," then:cd /cdrom/unixStep Three—Run the installation program “install” (or alternately, run the script "install_flow3d") Both scripts are in the current working directory:./install-or-./install_flow3dStep Four—The next dialog is the FLOW-3D License Agreement. Please read it carefully. If you agree to all the terms, click the Accept button to signify your agreement.Step Five – This dialog contains a default file location for FLOW-3D. If you wish for FLOW-3D to be installed in another location, modify the path and then click the Next button.Step Six – The next dialog displays the operating system types and installation types as shown here.Please select the “Local Operating System” that matches the device where you are currently installing FLOW-3D. Also, please select a “Type of Installation” from the list.Note: If this computer is only going to serve as your license server and you do not intend to run FLOW-3D on it, then you can choose to install “FLEX lm license server only.” On the other hand, if this computer is only a client, you should install only the FLOW-3D files.When you have selected an option in both catagories, click on the Install button and the installation will begin.Step Seven—Determine the "Host_ID" information.In order to receive your license file, you must first send Flow Science your computer’s Host_ID.If you are a new user, Flow Science will send you a "Customer License Issuance/Renewal Form" to fill out and return, and on this form you provide the necessary information. In filling out your information form, you must be careful to distinguish between the number zero "0" and the letter "o." You will also need to be careful to distinguish between the lower-case letter "l" and the number one "1."If you are an existing user, that is, you are using a new license server, send an email to Flow Science (licenses@) stating your name, the registered user’s name, your company name, and your telephone number. Include the file "host_id.txt" as an attachment.If you do not already know your computer’s Host_ID, you can find it out by running the script "get_host_id." Log on to the license server. Set your working directory to the "licenses" subdirectory in the distribution directory. One of the files in the "licenses" subdirectory is the script "get_host_id"; run this script to generate the output file "host_id.txt" which contains "host_id" information about your license server. For example, if the distribution directory is "/home/flow3d," then type:。

cast软件安装及使用
配置软件CAST的功能特点及设置CAST软件用于显示硬件MVX的序列号、许可证号、固件的版本号以及升级固件和配置硬件MVX的IP地址等。
1. CAST软件的安装安装CAST软件的PC机需具备以下配置和程序：·处理器PentiumIII，主频700M·操作系统：Windows2000或XP·推荐512M以上内存·最小的显示：1024×780·以太网端口100Mbits·需安装 Framework 2.0程序若没有安装 Framework 2.0程序，可打开数采器MVX光盘中MVX-3.1.1.x\ CSM+VIO_3.0.0.0 \Install .NET Framework 2.0进行安装。
安装CAST软件，打开数采器MVX光盘中MVX-3.1.1.x\CAST_3.1.x目录下的安装程序，在PC机中安装“CAST”的应用程序。
安装完成后可通过桌面上的快捷图标或开始菜单中的相应程序打开该程序2. CAST软件的配置与使用打开CAST软件，运行界面如下图所示，在Language项下选择English，然后选择“Configure”（该选项既可以读取数采器相关信息也可对数采器相关信息进行配置或写入，选择“Browse”选项可直接进入界面，但只能读取数采器信息），在Password中输入密码：OneproD（注意大小写）。
输入正确密码后，点击“Start”，将进入如下图所示的界面：在数采器MVX上有两个RJ45网络接口A和B，数采器MVX的RJ接口与PC机相似。
A端口为直通口：用一根直通线可接入网络中，用一根交叉线可实现与PC机点对点连接。
B端口为交叉口：用一根交叉线可接入网络中，用一根直通线可实现与PC机点对点连接。
下面以数采器MVX为出厂设置的状态为例，演示CAST程序的使用：当数采器MVX接入能够分配动态IP地址的网络时，在上图界面的IP Address or Serial Number框中输入数采器MVX的序列号，并且在密码栏Password框中输入大写的MVX，将出现下图所示的界面。
