- 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
  Maya HTT strives to release the best thermal-flow solver by continually updating and fixing critical issues and releasing monthly updates to the solver. The following section lists the most critical issues fixed starting in March 2024.

  - 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.

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.

Use the TMG Executive Menu application to do the following:

Run analyses in batch mode. You can use different input files such as INPF, thermal and flow solver scratch (XML) files, or multiphysics input .mpdat files.
Convert thermal and flow input files and run time files to and from different formats. For example, you can convert result binary files to the UNV format.
Remove unnecessary run time files from the running directories.
Run a thermal, flow, coupled thermal-flow, or multiphysics analysis in parallel on a cluster, using a scheduler.

Some processes depend on legacy NX I-deas TMG, NX I-deas ESC and Simcenter Femap TMG (11.4.1 or earlier) commands and do not work with files created by Simcenter 3D or Simcenter Femap TMG Thermal/Flow.

Location of executable

The TMG Executive Menu path and executable is:

<software installation>\nxcae_extras\tmg\com\tmgnx.cmd for Simcenter 3D or NX on Windows.
<software installation>\nxcae_extras\tmg\com\tmgnx.com for Simcenter 3D or NX on Linux.
<Femap installation>\tmg\femap\com\tmg.cmd for Simcenter Femap.

Note:

You can download the most recent TMG thermal-flow solvers installation from the downloads page for Simcenter 3D Add Ons or Femap Third Party Add Ons on Siemens Support Center.
