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 Designcenter, 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.
- 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 Windows 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.
    - Solve processes
      The following table lists all processes that solve different thermal-flow input files, their corresponding command prompt switch, and their description. These processes are listed in MAYA HTT TMG Executive when you select Solve from the Process Filter list.
    - Translation processes
      The following table lists all processes that translate thermal-flow input or run-time files to or from other formats, their corresponding command prompt switch, and their description. These processes are listed in MAYA HTT TMG Executive when you select Translation from the Process Filter list.
    - Results processes
      The following table lists all processes that manipulate thermal-flow result files, their corresponding command prompt switch, and their description. These processes are listed in MAYA HTT TMG Executive when you select Results from the Process Filter list.
    - File cleaning processes
      The following table lists all processes that remove unnecessary thermal-flow run-time files from the running folders, their corresponding command prompt switch, and their description. These processes are listed in MAYA HTT TMG Executive when you select File from the Process Filter list.
    - Other processes
      The following table lists all other processes, their corresponding command prompt switch, and their description. These processes are listed in MAYA HTT TMG Executive when you select Other from the Process Filter list.
    - Command prompt only processes
      The following table lists processes that are available only from the command prompt, 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.
- Solver supported compilers per version
  For each released version of the TMG thermal-flow solvers, the following table lists the compiler version that you can use when you compile your subroutine, thermal solver plugin function for expressions, or flow solver plugin function.
- Solver supported GPU cards per version
  The following table lists the supported graphics processing unit (GPU) requirements for accelerated thermal radiation computation by solver version.
- 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.
Thermal Solver
Contains thermal solver related guides, such as the TMG reference manual, thermal solver customization guide, and error message list.
Flow Solver
Contains flow solver related guides, such as the reference and customization guides.
TMG 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.

Command prompt only processes

The following table lists processes that are available only from the command prompt, their corresponding command prompt switch, and their description.


Switch	Process name	Description
TS	Purge all files and run TMG analysis from scxtmg.dat	Deletes all thermal solver run time files, then runs a thermal analysis using the local scratch file scxtmg.dat. The scxtmg.dat file is the thermal solver input file from which INPF is created for legacy NX I-deas TMG and Simcenter Femap TMG (11.4.1 or earlier) applications.
ND	Run analysis from XML, using DMP (scheduler) mode	Runs a thermal, flow, or coupled thermal-flow analysis in parallel on a cluster, using a scheduler.
RA	Merge ANSYS with TMG files and run TMG	(Obsolete) Merges an ANSYS database file with a thermal input file, runs the thermal analysis, and recovers temperatures in ANSYS format for legacy NX I-deas TMG, NX I-deas ESC, and Simcenter Femap TMG (11.4.1 or earlier) applications. The ANSYS database file is generated with the `CDWRITE` command.
PT	Starts the Parallel Configuration Tool program	Opens the Parallel Configuration Tool to let you create or modify the parallel configuration XML file and validate computers for parallel processing.
RP	Change parameter while the ANALYZER module is running	Allows you to change thermal parameters while solving a thermal analysis. The solution process must be in the ANALYZER module of the thermal solver.
UI	Start TMG Executive Menu GUI	Opens the MAYA HTT TMG Executive dialog box.
VA	View all commands	Lists all TMG Executive Menu processes that are available from the command prompt.
EX	Exit	Closes the TMG Executive Menu application.
