- 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 Designcenter, and Simcenter Femap. Older versions of TMG thermal-flow solvers are also included in NX I-deas.

Solve a solution from the command prompt

This example shows how to solve a Simcenter 3D solution from the Windows command prompt instead of starting the TMG Executive Menu user interface.

Set the required environment variables for the software from which you run the TMG thermal-flow solvers.

This task assumes that you run a TMG Executive Menu included with Simcenter 3D. Similar commands can be used with Simcenter Femap instead of Simcenter 3D when you change the environment variable and the executable name and location.

In the Windows command prompt, type the following command to launch the TMG Executive Menu application and press Enter:
```
%UGII_TMG_DIR%\com\tmgnx.cmd
```
This starts the TMG Executive Menu application in the text mode directly in the command prompt, which lists command prompt switches and prompts you to enter the desired switch. For each switch you use, the application guides you through all the information it requires. The switches are not case sensitive.
Type NX and press Enter.
The NX switch is equivalent to the Run analysis from XML, in solution's run directory process listed in Solve processes. Through the command prompt you can solve only one solution at a time.
Type the absolute or relative path to the solution input XML file and press Enter.

This starts the Solution Monitor, which runs the analysis.

Alternatively, you can combine the first two steps as follows in the command prompt, which requests the path to the XML file before solving:

%UGII_TMG_DIR%\com\tmgnx.cmd nx

You can also combine all three steps as follows:

%UGII_TMG_DIR%\com\tmgnx.cmd nx -inPath <path to the XML file>

Assuming you navigated in the command prompt to a folder that contains the sub folder named Test1 with the solution input XML file named Simulation1-Solution1.xml, use the following command:

%UGII_TMG_DIR%\com\tmgnx.cmd nx -inPath Test1/Simulation1-Solution1.xml

Because the solution input file in the Simcenter 3D Multiphysics solver environment has the .mpdat extension, use mp or mn switches instead nx:

%UGII_TMG_DIR%\com\tmgnx.cmd mp -inPath <path to the MPDAT file>
