Any arguments given are passedto the ANSYS Solver as command line arguments.For details, see MultiField Tab.-ansys-input <file> For an ANSYS Multi-field run, specifies theANSYS input file to use. For details, seeMultiField Tab.-ansys-input-is-complete For an ANSYS Multi-field run, this turns off theProcessing ANSYS Input File option. For details,see MultiField Tab.-ansys-installation <directory>For an ANSYS Multi-field run, gives the ANSYSinstallation directory. Only needed if ANSYS isinstalled in a non-standard location. For details,see MultiField Tab.-ansys-jobname <name>For an ANSYS Multi-field run, gives the jobname for the ANSYS part of the run. The ANSYS CFX-Solver Manager defaults this to ANSYS. On a restart, the jobname must be the same as for an initial run.-ansys-license <license>For an ANSYS Multi-field run, tells the ANSYS Solver which license to check out. For details, see MultiField Tab.-ansys-restart <file>For an ANSYS Multi-field run, tells CFX that the ANSYS part of the run is a restart, and gives the database (*.db or *.rdb) from the previous ANSYS run to be used for the restart. For details, see MultiField Tab.-bak-elapsed-time <elapsed time frequency>-baket <elapsed timefrequency>This will cause the flow solver to write a backupfile every <elapsed time frequency> minutes,hours, seconds, etc... Elapsed time must be inquotes and have units in square brackets. e.g.: -baket “10 [min]” or -baket “5 [hr]”.-batch Run ANSYS CFX-Solver in batch mode (i.e., without starting the ANSYS CFX-Solver Manager). This is the default mode.-ccl <file>Reads additional Command Language from the named file. Overrides any ANSYS CFX Command Language specified in the definition file.-cplg-host<port>@<host>For an ANSYS Multi-field run, tells the CFX Solver which Port Number and Host Name to use to communicate with the ANSYS Solver. For details, see MultiField Tab.-cplg-slave <name>For an ANSYS Multi-field run, tells the CFX Solver to operate as a coupling slave and to use the specified <name>to identify itself when it connects to the coupling master.In general, <name> should be CFX.-definition <file>-def <file>Use <file> as the input file, which may be a ANSYS CFX definition file or a results file for a restart. The file specified is used in the same way as the input file on the Define Run dialog box. For details, see Define Run Command.-display <display>(UNIX only) Use the X11 server <display> instead of the X11 server defined by the DISPLAY environment variable.-double Runs the double precision version of ANSYS CFX-Solver. See -single.-example <file>-eg <file>Runs the ANSYS CFX-Solver on one of the ANSYS CFX Example definition files provided with the product. The option StaticMixer is currently available.-help-h Displays help information.-initial <file>-ini <file>Use the initial values in the ANSYS CFX resultsfile <file>. This option may only be used together with a ANSYS CFX definition file which wascreated with the Automatic or Automatic with Value initialization settings. The file specified is used in the same way as the initial values file inthe Define Run dialog box. For details, see DefineRun Command.-interactive-int-manager Run the interactive ANSYS CFX-Solver Manager to start a new run and/or manage or monitor an existing run.Sets the maximum elapsed time (wall clock time)-max-elapsed-time <elapsed time>-maxet <elapsed time>that the CFX solver will run. Elapsed time must bein quotes and have correct units in square brackets.eg: -maxet “10 [min]” or -maxet “5 [hr]”.-mfx-run-mode <"Start ANSYS and CFX"|"Start ANSYS only"|"Start CFX only"|"Process Input File only">Specifies the MFX run mode for an ANSYS Multi-field run. You can choose to start both ANSYS and CFX solvers, just ANSYS, just CFX, or process the ANSYS input file only. For details, see MultiField Tab.-monitor <file>When starting Solver Manager, monitor the run represented by <file>, which may be a ANSYS CFX results file or output file.-name <name>Choose names for the exported files and temporary directory based on the problem name <name> instead of the definition file name unless other names are explicitly defined.This name cannot be set when using the ANSYS CFX-Solver Manager to start the ANSYS CFX-Solver.-parallel-par Runs the solver in parallel mode. This option can be combined with -partition for a partitioning run.-par-local Allows fast setup of a parallel run on the local host only.-par-dist Allows fast setup of a distributed parallel run. See the examples below.-par-host-list <host1>, [<host2>,...]When running in parallel, do not use the list of hosts in the host file passed in through the -hstfile argument. Instead, use the list from this argument. If the -hstfile argument is also given,host details are taken from that file if possible, if the -hstfile argument is not given, or if any of the specified hosts are not available in the file so named, details are read from l file which is also used by Solver Manager.-parfile-read <parfile>Specifies the name of an input partition file used to set up a partitioning or parallel run.-parfile-write <parfile>Specifies the name of a partition file to write to, containing the information from a partitioning run.-partition<#partitions>-part <#partitions>Runs the solver in partitioning mode. Thespecified <#partitions> must also be specifiedas a dummy value if a par file is also specified andthe required number of partitions is taken from thisfile.-partitioner <executable>Run <executable> instead of the standard partitioner.-part-large Runs the large problem partitioner which can partition problems up to 2^32-1 elements. This partitioner uses 64 bit integer and logical variables so it will allocate more memory than the default partitioning executable.-part-only <# of partitions>Runs the solver in partitioning mode only. This is normally equivalent to -part, but may be necessary if partitioning a results file from a previous run.-part-mode <mode>Sets the partitioning mode to use when running the partitioner. Valid options are metis-kway, metis-rec, rcbFiner control over the partitioning method is available through the Command Language.-priority <number>-pri <number>Allows the specification of a job priority to a solver run. Priority 2 is the default priority setting, with priority 1 being lower than the default. High priorities can be set with 3 and 4.-save Do not delete any temporary files after the run. Normally the standard temporary files created by ANSYS CFX-Solver are deleted automatically after each run.-serial If restarting from a results file produced by a parallel run, this forces the run to be done in serial.-single Runs the single-precision version of the ANSYS CFX-Solver. This is the default, but is provided for overriding any information which might be stored in the CFX Command Language dataset in a file from a previous run. See -double.-size <factor>-s <factor>Change memory estimates used by the ANSYS CFX-Solver by a factor of <factor>. Memory estimates are sometimes inaccurate and this option needs to be used to increase the memory allocated. For example, using -size 1.05increases memory allocated by 5%. This option provides the same functionality as set in Solver Memory. For details, see Solver Tab.Further options for controlling the ANSYS CFX-Solver memory allocation are available. Execute cfx5solve -help for full details.-size-mms <factor>-smms <factor>Change the initial MMS catalogue space estimate used by the ANSYS CFX-Solver by a factor of <factor>.-size-part <factor>-sizepar <factor>Change the memory estimates used by the partitioner by a factor of <factor>.
