hello,
i would be obliged if someone can please inform me as to how to utilize a RTX with Converge CFD simulation.
Regards.

Hi, If you were asking how to use the GPU to accelerate your CONVERGE simulation, since CONVERGE v3.1, GPU computation is available for the pressure solver (only). To enable it, please turn the "inputs.in > accelerator_control >use_gpu _flag" to 1, also you need use the CONVERGE_ BICGSTAB _ GPU as your pressure equation solver by making "solver.in > Transport > pres > solver_ type = CONVERGE_ BICGSTAB".

Hope it helps.

PLEASE ACCEPT MY SINCERE GRATITUDE. THANK YOU SO MUCH.
i wanted to know also if it can also help chemistry solve faster through the advised procedure. My interest is only in IC engine simulation with Sage.
i thank you again for reaching out to my post.
regards

Hey Rahul,


We are currently in the process of improving GPU speedup, thus we have temporarily discontinued it in the new version. Until then we do not recommend using GPU for CONVERGE,

Thanks

thank you for reaching out with a specific answer. I appreciate it. Can you give an approximate period till which we may expect to see GPU participation.

Regards
Rahul

Hey Rahul,


Unfortunately we do not have an approximate period for availability of GPU version.

Thanks
