Hi All<\/p>\n

I tried enabling GPU acceleration on ANSYS Mechanical but I am not sure whether the GPU is being utilized in the processing. I have done the following as of now<\/p>\n

1) Set the ANSGPU_OVERRIDE variable to 1.<\/p>\n

2) Enabled the number of GPU to be used in the solver settings to 2.<\/p>\n

I still get the following on the solver output file<\/p>\n

"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."<\/p>\n

My Machine is a Dell Precision 7920 Tower with 48 physical cores, 256 GB RAM and 2*16 GB GPU NVIDIA Quadro RTX 5000. <\/p>\n

Any help would be appreciated!<\/p>\n

Thank you <\/p>\n
