Hello,

My research group is trying to model a two-way Fluid Structure Interaction (FSI) using the Fluent and Transient Structural modules available in the ANSYS Suite. Our simulation times, at the moment, are around a day for a total simulation time of 2 seconds. We'd like to reduce the total computational time from a day to something more manageable and to that end, would like to upgrade our desktop/components of the desktop. This is our current configuration:

• INTEL i9-13900 CPU
• 32 GB DDR5 RAM
• NVIDIA T1000 8 GB GPU
• 1 TB SSD

What would you recommend that we upgrade to see the best return on investment? Additionally, is there a way to make ANSYS use the GPU to solve the simulation that would result in a lower computational time as compared to using the CPU and if so, what GPU would you recommend?

 

Thank you

Hi,

I hope you are running Ansys 2024 R1 or ideally 2024 R2 now. I am suggesting a two pronged approach to your concerns.

Firstly, opening another thread to focus on the model aspects, physics involved, setup, timestep, which results are being calculated and stored and how often, and importantly the model size and thus computational demands and using 

Second - would be how to ensure optimal execution and additional or replacement hardware to speed up the process.

for GPU Acceleration and GPU compute please see see the PDF files linked here named accordingly
