Thermal-Flow
Contains general thermal and flow solver related documentation, such as the verification test cases, monthly critical fixes, DMP guide, and knowledge base articles.
- TMG thermal-flow solvers
  Maya HTT develops and maintains a thermal solver and a flow solver, which are combined into the TMG thermal-flow solvers. These solvers are included and distributed with Simcenter 3D, NX, and Simcenter Femap. Older versions of TMG thermal-flow solvers are also included in NX I-deas.
- Thermal and flow verification test cases
  Contains verification test cases for the thermal and flow solvers.
- Monthly critical fixes
  Lists critical bugs that are fixed monthly for the thermal and flow solvers.
- TMG Executive Menu
  TMG Executive Menu is a standalone application that lets you execute processes on thermal-flow files and solutions independently of Simcenter 3D or Simcenter Femap.
  - Start TMG Executive Menu
    This example shows how to start TMG Executive Menu to open the MAYA HTT TMG Executive dialog box.
  - Solve a solution from the command prompt
    This example shows how to solve a Simcenter 3D solution from the command prompt instead of starting the TMG Executive Menu user interface.
  - Run solutions from the user interface
    This example shows how to solve multiple thermal and flow solutions from XML input files in batch mode from the TMG Executive Menu user interface.
  - Run solutions using a BAT file
    Depending on the command switch you use, you can launch batch runs using the Windows cmd command. The following page presents sample code examples and explanations.
  - TMG Executive Menu process descriptions
    The tables on following pages list all available TMG Executive Menu processes, their corresponding command prompt switch, and their description.
  - MAYA HTT TMG Executive dialog box
    The MAYA HTT TMG Executive dialog box opens when you start the TMG Executive Menu application with the UI command prompt switch.
- Thermal and flow DMP guide
  Describes the general workflow for executing the simulation jobs using distributed memory parallel processing on clusters and the scheduler-dependent files required to submit the jobs to the scheduler.
- Thermal-flow data exchange files
  The thermal and flow solvers in Simcenter 3D and Simcenter Femap create multiple thermal-flow data exchange files described on the following page.

Run solutions using a BAT file

Depending on the command switch you use, you can launch batch runs using the Windows cmd command. The following page presents sample code examples and explanations.

Copy the code from these examples to add them to a BAT file. To run, just double-click your BAT file from the Windows file explorer. Alternatively, you can use the following examples directly in a Windows command prompt.

Example 1: run analysis from XML, in solution’s run directory

set UGII_TMG_DIR=[Simcenter 3D installation]\NXCAE_EXTRAS\tmg

%UGII_TMG_DIR%\\com
tmgnx.cmd NX

Specify the correct absolute path to the Simcenter 3D installation when setting the UGII_TMG_DIR environment variable.

Note:

You can omit this first line if the UGII_TMG_DIR environment variable is globally set on your computer.

Example 2: run analysis from XML, in file directory

In this example, it is assumed that the UGII_TMG_DIR environment variable is already set.

%UGII_TMG_DIR%\\com
tmgnx.cmd NF

You can use this command in a Python code as follows:

os.chdir(directory) # Change directory to current xml location
    subprocess_cmd('set UGII_TMG_DIR='UGII_TMG_DIR'&%UGII_TMG_DIR%\\com
tmgnx.cmd NF -inPath '+ Runs[num2] +'_mod.xml')

In this code snippet, the subprocess_cmd function, which starts a shell command, and the values of the directory, UGII_TMG_DIR, and Runs[num2] variables must first be provided. '+ Runs[num2] +'_mod.xml indicates the path to the XML file.

Example 3: run thermal analyses in specified directories

In this example, you run simultaneously three thermal analyses from INPF, which are stored in the Run1, Run2, and Run3 folders. The commands must be run from the folder containing the Run1, Run2, and Run3 folders.

set UGII_TMG_DIR=[Simcenter 3D installation]\NXCAE_EXTRAS\tmg
FOR /L %%G IN (1,1,3) DO START /D .\Run%%G %UGII_TMG_DIR%\\com
tmgnx.cmd TA

These commands set the UGII_TMG_DIR environment variable, loops through the range 1 to 3, and starts TMG Executive Menu in Run1, Run2, and Run3 folders, respectively.
