GAMBIT用户手册_4_GAMBIT菜单命令
4.GAMBIT菜单命令GAMBIT的主菜单条包括下列菜单命令：菜单项作用File•建立、打开和保存进程•打印图形•编辑和/或运行日志文件•删除日志文件•查看文本文件•导入和导出几何结构和网格数据•退出程序Edit•编辑进程名称•编辑文本文件•建立和编辑参数•编辑程序默认属性Solver•选定一个解算器Help•进入在线帮助文档本章的以下部分将阐述上面这些主菜单命令的功能和用法。
注意，在以下章节中的多数定义窗口中将包括和两个按钮。
除非特别说明，这两个按钮的功能如下：—Accept——执行与该窗口相关的操作。
—Close——关闭该窗口而不执行相关操作。
4.1File命令GAMBIT的File菜单包含如下命令：命令说明New创建一个新的进程Open打开一个以前保存过的进程Save保存当前进程Save As以一个新的名称保存当前进程Print Graphics打印当前显示的图形Run Journal 显示并允许用户编辑和执行任何日志文件中的命令Clean Journal从GAMBIT日志文件中删除外部命令、信息和符号View File 显示当前的文本文件Import导入几何结构和网格数据Export导出几何结构和网格数据Exit终止程序的执行4.1.1 New当用户从File菜单中选择了New，GAMBIT打开Create New Session窗口。
Create New Session窗口允许用户建立和命名一个新进程。
要创建一个新的进程，用户必须指定如下项目：—进程标识—保存选项另外，除了上述两项，GAMBIT也允许用户设定进程的标题。
进程标识包含与该新进程相关联的GAMBIT数据文件的基本名称。
（有关数据文件的内容和格式的说明，请参阅本向导的第二章。
）保存选项决定GAMBIT在建立新进程之前是否保存现有进程的数据。
进程标题包含了该进程的一般说明。
定义进程标识进程标识可以由任意的字母组合和/或GAMBIT所运行的系统环境下允许的有效文件名中所包含的符号组成。
Gambit使用教程(三维)
图12
5．创建一个直径60mm，高180mm的圆柱，将其沿X轴移动36mm（图13）。
图13
6．利用uion命令，将视图中所有的几何体合成一个几何体volume1。
7．创建一个长216，宽60，高60的长方体，将其沿Y轴移动-30个单位。
（一）在Autocad中创建维多辛斯基曲线
1．利用pline命令将维多辛斯基曲线上的各点坐标连成一条折线。
2．利用pedit命令使折线光滑。
3．创建其他轮廓线（见图2）。
喷嘴的具体参数见参考图纸。
图2 CAD中创建的喷嘴轮廓线
（二）输出为ACIS的.sat文件
对于二维图形要输出为.sat文件，必须是一个region图形。
3．划分外区域的网格，网格类型为submap（见图8）。
图8
（六）定义边界条件
1．选择solver/fluent5。
2．单击 按钮。
3．定义各边界条件。
4．单击 ，将两个面设为同一个连续体（fluid）（见图9）
图9
注意：对于一个复杂的几何体而言，在网格划分时必定要划分为多个区域。将这些区域定义到一个统一的连续体中，这样，不同区域间的分隔线就会被默认为内部网格点。
图6
2．喷嘴外部的面（face2），定义轴线上网格点为240个。定义喷嘴外轮廓线的网格点数（见图7）
图7
注意：对于网格的划分，如果要求控制网格的密度，可以遵循从线到面的原则，但是对于多边形区域而言，不能将所有边的网格点都定死，必须有一些边不定义网格。如四边形区域，一般只定义相邻两个边的网格。至于多边形区域怎样定义边上的网格，必须在实践中不断的尝试。

第一章介绍本向导的目的在于分类和描述通过GAMBIT GUI有效的操作。
本向导的逻辑结构遵从Operation工具框和与之相关的子工具框。
也就是说，章节、部分和子部分的组织反应了GUI 上命令按钮的层次。
例如，第二章、第三章、第四章和第五章分别阐述了与命令按钮Geometry、Mesh、Zones和Tools相关的操作，它反应了这些命令按钮在Operation工具框中显示的顺序（如图1所示）。
图1－1：Operation工具框类似的，Blend Volumes操作的详细说明在Volume Boolean操作说明之后，因为在Geometry/ Volume子工具框中它的命令按钮工具框位于Boolean命令按钮的右边（如图1－2所示）。
图1－2：Geometry/Volume子工具框1.1格式和字体的规定GAMBIT User's Guide的第一章阐述了用于整个向导的基本格式和字体的规定。
为了方便起见，在此再次说明格式和字体的规定。
1.1.1格式的规定本向导使用两种标准格式。
•图形格式•版面格式图形格式决定了在GAMBIT GUI中用于代表控制单元和命令按钮的符号类型。
版面格式决定了GAMBIT设定窗口的描述结构。
图形格式使用了两种基本类型的用户界面组件。
•控制单元•工具框命令按钮以下的部分详细说明用于整个文件中的规定来阐述上面列举的组件。
控制单元GAMBIT GUI使用诸如命令按钮、选择按钮和文本框等控制单元来使用户进行诸如执行动作、选择选项设置和输入字母数据等操作。
用于本向导的图形格式规定提供了如下的GAMBIT GUI控制单元。
控制单元示例图形格式功能命令按钮Command执行按钮标题所指示的命令。
选择按钮Option 1从互斥选项菜单中选择。
Option 2…文本框Value从键盘上接受字符数据。
窗口标题Heading:指定按钮和选项组的一般功能单选按钮Option从显示的互斥选项菜单中选择。
GAMBIT使用说明
GAMBIT使用说明GAMBIT是使用FLUENT进行计算的第一个步骤。
在GAMBIT 中我们将完成对计算模型的基本定义和初始化，并输出初始化结果供FLUENT的计算需要。
以下是使用GAMBIT的基本步骤。
1．1定义模型的基本几何形状如左图所示的按钮就是用于构造模型的基本几何形状的。
当按下这个按钮时，将出现如下5个按钮，它们分别是用以定义点、线、面、体的几何形状的。
值得注意的是我们定义这些基本的几何元素的一般是依照以下的顺序：点——线（两点确定一线）——面（3线以上确定一面）——体（3面以上确定体）对各种几何元素的操作基本方式是：首先选中所要进行的操作，再定义完成操作所要的其他元素，作后点“APPLY”按钮完成操作。
以下不一一重复。
下面我们分别介绍各个几何元素的确定方法：1．1．1点的操作对点的操作在按下点操作按钮后进行（其他几何元素的操作也是这样）。
点有以下几种主要操作定义点的位置按钮，按下后出现下面对话框Coordinate Sys.：用以选择已有坐标系中进行当前操作的坐标系T ype：可以选择3种相对坐标系为当前坐标系：笛卡儿坐标、柱坐标、球坐标。
以下通过在Global 中直接输入点的x、y、z值定义点，注意这里的坐标值是绝对坐标值，而Local中输入的是相对坐标值，一般我们使用绝对坐标值。
Label:为所定义的点命名。
在完成以上定义后就可以通过进行这个点的定义，同时屏幕左半部的绘图区中将出现被定义的点。
用关闭此对话框。
查看所有点的几何参数按钮（在以后的操作中也可以查看其他元素的几何参数）在Vertices栏中选择被查询的点，有两种选择方式（其他几何元素的选择与此类似）：①按住shift键的同时用鼠标左键取点②点按钮，选择查询点选择后进行“APPLY”完成操作，可在屏幕左下角Transcript框中看查询结果。
1．1．2线的操作线操作按钮下面介绍主要的几种线操作定义直线按钮定义直线的前提是有两个点，两点确定一条直线。

史上最详细的Gambit教程 不看后悔
Gambit建模简例教程2008年10月李宏刚本文通过建立一个简单的二维车身流场有限元模型，来说明应用Gambit建模的基本方法。
建模的方法不是唯一的，只有通过不断学习和实践才能更好的掌握。
与其他工程软件需要工作目录一样，Gambit也需要一个指定的目录来建立所需要的相关文件。
（注：文件名、工作目录及其所在路径最好全部为英文字母或数字，不用中文，如路径中出现中文可能导致程序错误。
如：D:\gambitwork\examples\car1\car1.msh为正确的；D:\gambitwork\车身流场\car1\car1.msh可能导致错误。
）因此，首先建立一个文件夹（通常最好一个有限元分析模型建立一个文件夹），用来存放生成的Gambit文件和一些Gambit自动生成的临时文件等，本例在D盘根目录建立一个名为gfiles的文件夹。
然后启动Gambit。
如下图示。
点击Gambit 2.3.16出现如下窗口。
单击Browse按钮，选择已经建立的工作目录d:\gfiles，点OK。
在Session Id栏中输入建立的工程文件名，我们这里输入car1。
（以后再次对该文件进行编辑时，在右侧的下拉列表中直接选取该文件即可，如遇到无法打开的情况，可将目录中的*.lok文件删除后再试。
）单击Run 后进入Gambit 主界面，如下。
一、Gambit 的操作界面如上图所示，Gambit 用户界面可分为7个部分，分别为：菜单栏、视图、命令面板、命令显示窗、命令解释窗、命令输入窗和视图控制面板。
文件栏文件栏位于操作界面的上方，其最常用的功能就是File 命令下的New 、Open 、Save 、Save as 和Export 等命令。
这些命令的使用和一般的软件一样。
Gambit 可识别的文件后缀为.dbs ，而要将Gambit 中建立的网格模型调入Fluent 使用，则需要将其输出为.msh 文件(file/export)。
Gambit使用教程
三维建模相对于二维建模而言，三维建模与二维建模的思路有着较大的区别。
二维建模主要遵循点、线、面的原则，而三维建模则更象搭积木一样，由不同的三维基本造型拼凑而成，因此在建模的过程中更多的用到了布尔运算及Autocad等其他的建模辅助工具。
三视图的使用在建立三维图形的时候，使用三视图有利于我们更好的理解图形。
图30显示的是Gambit的视图控制面板。
图30在当前状况下，四个视图都是激活的（在Active栏中，显示红色），这时视图控制面板中的十个命令将同时作用于四个视图。
在创建三维图形之前，我们要做的第一项工作就是要将Gambit的四个视图设置为顶视图、前视图、左视图和透视图。
1．用鼠标单击Active右边的后三个视图，取消对它们的激活，激活取消后呈灰色（见图31）。
图312．用鼠标右键单击视图控制面板中的坐标按钮，弹出一组坐标系（见图32）。
3．选择，则左上视图变成顶视图。
如法炮制，设置其他视图（见图33）。
4．单击控制面板中的，也可将视图设成三视图。
图32图33基本三维模型的建立在Gambit控制面板中单击按钮，在Volume中用鼠标右键单击，弹出一组按钮（见图34），表示Gambit所能创建的基本三维几何体，主要有长方体、圆柱体等。
图34布尔运算的基本概念典型的布尔运算包括并、交、减。
并：将两个物体并成一个物体（两个物体的并集）交：两个物体的交集减：A物体减去B物体下面用一个简单的例子来说明基本三维几何体的创建和布尔运算的运用1．单击按钮，输入参数创建一个高60，半径6的圆柱体（见图35）。
在Axial Loaction栏中选取Positive X，使得圆柱体的法线指向x方向。
在Gambit中创建的几何体，其基点都在坐标系的原点（见图36）。
如果创建的几何体过大，在视图中无法显示全图，或者太小，无法分辨，单击按钮即可。
图35图362．为了能够更好的观察三维几何体，可以用鼠标拖动四个视图中央的小方块，改变四个视图的大小（见图37）。

第一章介绍本向导的目的在于分类和描述通过GAMBIT GUI有效的操作。
本向导的逻辑结构遵从Operation工具框和与之相关的子工具框。
也就是说，章节、部分和子部分的组织反应了GUI 上命令按钮的层次。
例如，第二章、第三章、第四章和第五章分别阐述了与命令按钮Geometry、Mesh、Zones和Tools相关的操作，它反应了这些命令按钮在Operation工具框中显示的顺序（如图1所示）。
图1－1：Operation工具框类似的，Blend Volumes操作的详细说明在Volume Boolean操作说明之后，因为在Geometry/ Volume子工具框中它的命令按钮工具框位于Boolean命令按钮的右边（如图1－2所示）。

下面仍然以二维轴对称自由射流的网格划分为例，来介绍各种网格的生成。
1．单击命令面板中的 按钮（Mesh Face），进入面的网格创建命令面板（见图25）。
图25
2．选择视图中的面，系统中默认的网格点的类型为四边形结构网格。单击Apply按钮，观察网格的生成（见图26）。
视图控制面板中常用的命令有：
全图显示、 选择显示视图、 选择视图坐标、 选择显示项目、 渲染方式。
同时，我们还可以使用鼠标来控制视图中的模型显示。其中按住左键拖曳鼠标可以旋转视图，按住中键拖动鼠标则可以在视图中移动物体，按住右键上下拖动鼠标可以缩放视图中的物体。
命令面板
命令面板是Gambit的核心部分，通过命令面板上的命令图标，我们可以完成绝大部分网格划分的工作。
图26
3．在命令面板的Type中选择网格类型为Pave，单击Apply按钮，观察网格的生成（见图27）。
图27
4．选择Element类型为Tri，单击Apply按钮，观察网格的生成（见图28）。

三．
在Gambit中，我们可以先定义好各个边界条件的类型，具体的边界条件取值在Fluent中确定。
1．在菜单栏中选择Fluent/Fluent5。这个步骤是不可缺少的，它相当于给Gambit定义了一个环境变量，设置完之后，定义的边界条件类型和Fluent5中的边界类型相对应。
命令显示窗和命令输入栏
命令显示窗和命令输入栏位于Gambit的左下方（如图4所示）。

GAMBIT使用说明
GAMBIT使用说明GAMBIT使用说明GAMBIT是使用FLUENT进行计算的第一个步骤。
在GAMBIT 中我们将完成对计算模型的基本定义和初始化，并输出初始化结果供FLUENT的计算需要。
以下是使用GAMBIT的基本步骤。
1．1定义模型的基本几何形状如左图所示的按钮就是用于构造模型的基本几何形状的。
当按下这个按钮时，将出现如下5个按钮，它们分别是用以定义点、线、面、体的几何形状的。
值得注意的是我们定义这些基本的几何元素的一般是依照以下的顺序：点——线（两点确定一线）——面（3线以上确定一面）——体（3面以上确定体）对各种几何元素的操作基本方式是：首先选中所要进行的操作，再定义完成操作所要的其他元素，作后点“APPLY”按钮完成操作。
以下不一一重复。
下面我们分别介绍各个几何元素的确定方法：1．1．1点的操作对点的操作在按下点操作按钮后进行（其他几何元素的操作也是这样）。
点有以下几种主要操作定义点的位置按钮，按下后出现下面对话框Coordinate Sys.：用以选择已有坐标系中进行当前操作的坐标系T ype：可以选择3种相对坐标系为当前坐标系：笛卡儿坐标、柱坐标、球坐标。
以下通过在Global 中直接输入点的x、y、z值定义点，注意这里的坐标值是绝对坐标值，而Local中输入的是相对坐标值，一般我们使用绝对坐标值。
Label:为所定义的点命名。
在完成以上定义后就可以通过进行这个点的定义，同时屏幕左半部的绘图区中将出现被定义的点。
用关闭此对话框。
查看所有点的几何参数按钮（在以后的操作中也可以查看其他元素的几何参数）在Vertices栏中选择被查询的点，有两种选择方式（其他几何元素的选择与此类似）：①按住shift键的同时用鼠标左键取点②点按钮，选择查询点选择后进行“APPLY”完成操作，可在屏幕左下角Transcript框中看查询结果。
1．1．2线的操作线操作按钮下面介绍主要的几种线操作定义直线按钮定义直线的前提是有两个点，两点确定一条直线。
Gambit使用教程中文版
第一章Gambit使用1.1Gambit介绍网格的划分使用Gambit软件，首先要启动Gambit，在Dos下输入Gambit<filemane>，文件名如果已经存在，要加上参数-old。
一．Gambit的操作界面图1Gambit操作界面如图1所示，Gambit用户界面可分为7个部分，分别为：菜单栏、视图、命令面板、命令显示窗、命令解释窗、命令输入窗和视图控制面板。
文件栏文件栏位于操作界面的上方，其最常用的功能就是File命令下的New、Open、Save、Save as和Export等命令。
这些命令的使用和一般的软件一样。
Gambit可识别的文件后缀为.dbs，而要将Gambit中建立的网格模型调入Fluent使用，则需要将其输出为.msh文件(file/export)。
视图和视图控制面板Gambit中可显示四个视图，以便于建立三维模型。
同时我们也可以只显示一个视图。
视图的坐标轴由视图控制面板来决定。
图2显示的是视图控制面板。
图2视图控制面板视图控制面板中的命令可分为两个部分，上面的一排四个图标表示的是四个视图，当激活视图图标时，视图控制面板中下方十个命令才会作用于该视图。
视图控制面板中常用的命令有：渲染方式。
同时，我们还可以使用鼠标来控制视图中的模型显示。
其中按住左键拖曳鼠标可以旋转视图，按住中键拖动鼠标则可以在视图中移动物体，按住右键上下拖动鼠标可以缩放视图中的物体。
命令面板命令面板是Gambit的核心部分，通过命令面板上的命令图标，我们可以完成绝大部分网格划分的工作。
图3显示的就是Gambit的命令面板。
图3Gambit的命令面板从命令面板中我们就可以看出，网格划分的工作可分为三个步骤：一是建立模型，二是划分网格，三是定义边界。
这三个部分分别对应着Operation区域中的前三个命令按钮Geometry(几何体)、mesh（网格）和Zones（区域）。
Operation中的第四个命令按钮Tools 则是用来定义视图中的坐标系统，一般取默认值。
