Hi 
I posted the following question on another platform:
——————————————————————————————–<\/p>\n

Hi
In ANSYS 2021 R2, I am able to set the number of processors and number of GPUs for the FLUENT simulation:<\/p>\n

<\/a><\/p>\n

But I am not able to do that in 2022 R2:<\/p>\n

<\/a><\/p>\n

Any advice? I am using a machine with 60 processors and 2 GPUs<\/p>\n

 <\/p>\n

Thanks<\/p>\n

————————————————————————————————-<\/p>\n

I then got the following helpful answer:<\/p>\n

Hi 1829116, 
As Erik correctly mentioned since it’s a structural mechanics forum so you can post this question in the fluent forum. but for your answer, you can click on the show more option and select a “parallel setting” and find the option of the “solver gpgpus per machine” to choose. I have highlighted the option so you can see it. 
<\/a><\/p>\n

Regards,
Sampat<\/p>\n

I do have a followup question thou. Can I change the numer of GPUs after I have started a simulation? Usually I can do that for the number of processes from properties of the solution in Workbench. Any similar method for the number of GPUs<\/p>\n

 <\/p>\n

Thanks<\/p>\n
