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.
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
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.
- 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.

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.


TMG version	Supported CUDA version	GPU architecture	Compute capability	Note
2412 - 2506.6	NVIDIA CUDA 12.4 or later	Maxwell to Hopper	5.0 - 9.0	With CUDA 12.4, support for GPU architectures prior to Maxwell is deprecated.
2506.7-2512	NVIDIA CUDA 12.9 or later	Maxwell to Blackwell	5.0 – 12.1	With CUDA 12.9, support for GPU architectures prior to Maxwell is deprecated.
2606	NVIDIA CUDA 13.0.2 or later	Turing or later	7.5 and up	With CUDA 13.0, support for GPU architectures prior to Turing is deprecated.

Recommendations

On Windows, the operating system may terminate the GPU driver to prevent an OS crash when the GPU is busy, the GPU computation load is high, or rendering takes more than a few seconds. This can cause the thermal solver to crash. To help prevent these crashes, we recommend:

Extending the Timeout Detection and Recovery (TDR) delay in the Windows registry to specify how long Windows waits before terminating the GPU driver.
Dedicating one GPU to OS rendering and the other GPU to the software if your machine has two GPUs.
