請問如何使用CUDA運算? How to run simulation or analyze with CUDA ? 
需要 QUADRO 顯卡 或者是否可以用一般的GTX顯卡? 
Is it need Quadro card or also can run with gtx card?

The Ansys APDL solver can make use of Nvidia GPUs to accelerate some parts of the solution process. 
Nvidia GPU cards used for solver acceleration require the CUDA libraries to accelerate the FEA solution.
The versions of Ansys 2024R2 and greater include the required CUDA libraries and do not need to be installed separately. 

Quadro or GTX cards are not supported. 

Your system must meet the following requirements to use the GPU accelerator capability in Mechanical APDL. For information on the most recently tested NVIDIA GPU cards, see the GPU Accelerator Capabilities PDF on the Platform Support section of the Ansys Website.

• The machine(s) being used for the simulation must contain at least one NVIDIA GPU card.

 

• A minimum 16GB of on-card memory is recommended in order to achieve meaningful acceleration in simulations that can use the NVIDIA GPU card.

 

• To achieve optimal performance, only NVIDIA GPU cards with significant double precision performance (FP64) are recommended for use with the sparse direct solver and eigensolvers based on the sparse solver (for example, Block Lanczos or subspace). The following cards are recommended:

 

	Recommended Solvers
Card	Release Year	Sparse (Direct)	Iterative (PCG, etc.)	Mixed
NVIDIA B100	2024	Y	Y	Y
NVIDIA A800	2024	Y	Y	Y
NVIDIA H100	2022	Y	Y	Y
NVIDIA A30	2021	Y	Y	Y
NVIDIA A100	2020	Y	Y	Y
NVIDIA RTX 5880 Ada	2024	N	Y	Y
NVIDIA RTX 5000 Ada, A4500 Ada	2023	N	Y	Y
NVIDIA L40	2022	N	Y	Y
NVIDIA RTX 6000 Ada	2022	N	Y	Y
NVIDIA RTX A5500	2022	N	Y	Y
NVIDIA A16, A10	2021	N	Y	Y
NVIDIA RTX A5000, A4500, A4000	2021	N	Y	Y
NVIDIA RTX A6000	2020	N	Y	Y
NVIDIA A40	2020	N	Y	Y

Let me know if this is helpful.
