Nvidia Quadro P4000 GPU Acceleration in Mechanical

      Hello, 


      I have a Quadro P4000 and it was not listed as tested GPU acceleration for the Mechanical on 2019 R3. I was looking at the discussions and found the following thread: https://studentcommunity.ansys.com/thread/gpu-acceleration-with-nivida-quadro-p4000/


      I followed the advice provided by Win and Peter and managed to start the simulation with GPU. However, as soon as it started this warning message popped up:


      The Distributed Sparse Matrix Solver was not able to sufficiently       


       utilize the GPU accelerator device(s) during this equation solution.    


       This can be caused by one or more factors such as: the size of the      


       system of equations being solved; using older or less powerful GPU      


       hardware relative to the CPU core(s) involved; having insufficient      


       available memory on the GPU device.  The check for GPU performance      


       terminates for the remainder of this session.   


       


      Initial my model had ~40,000 nodes & ~5,500 HEX20 elements, so I thought to myself maybe it is an issue related to the model size. I decreased the model size however I saw the same error message. Here are the hardware and the problem settings:


       


      - Intel i9 - 9900k 8 core processors


      - 32 GB of RAM


      - 512 GB of SSD


      - Transient analysis with linear elastic solids, frictionless contacts between adjacent faces, Direct solver, ~40,000 nodes & ~5,500 HEX20 elements


      Any comments or recommendations will be appreciated.

      Hi Utku,


      I am moving your post to "Installation and Licensing" category so you can get better assistance.

      Hi Utku,


      Just to make sure it has nothing to do with the project, please try creating a simple cube and use static structural with simple BC's and coarse mesh , then see if you get the same warning/error about GPU.


      If you still see it, try updating your graphics driver to the latest from Nvidia website

      Thanks,


      Win
