Hi,

I am a student at the University at Buffalo using ANSYS Workbench Components for my research, particularly Material Designer, SpaceClaim, AutoDYN, and Explicit Dynamics. I was allocated a system named Taz in my lab, but it’s a university-owned system, so I don't have administrative control over it.

My goal is to run ANSYS Workbench simulations directly from Taz on the university's high-performance computing cluster (HPC), which is called . In the past, I would create files on my system, transfer them to , the HPC GUI, and then run the simulations there.

I'd like to improve the efficiency of this process by running the simulations directly from Taz on the HPC. However, I contacted the University IT department and the HPC department for assistance. The IT department was unsure how to do this, and the HPC department said installing RSM on the login nodes is not possible.

Since I have no prior experience working with clusters, I am hoping someone can guide me through setting up this process to run simulations on the HPC from Taz.

Please let me know if you need any additional information.

Thanks,

Amrith

@Amrith, This forum is public, meaning, anyone can see what you post here. Please refrain from posting Personally Identifiable information here. I have removed all the links that you used, along with images that had emails of university folks. I would recommend going through the forum rules and guidelines before posting on the forum once!

To simulate on a cluster without RSM or cloud, you would typically need to manually transfer the simulation files to the cluster and use the cluster's job scheduling system to execute the simulation. This process can vary depending on the specific cluster setup and the job scheduler in use (e.g., Slurm, PBS, etc.). You will need to write a job script that loads the necessary Ansys modules, sets up the environment, and runs the simulation executable with the correct command-line arguments.

Please note that Material Designer and SpaceClaim won't be supported on Linux (https://www.ansys.com/content/dam/it-solutions/platform-support/2024-r1/ansys-2024-r1-platform-support-by-application.pdf), so the best way would be to create all geometry-related data locally (or on Windows cluster) and then use the scripts to run the solver. I think you are getting as much as you can without installing RSM for now.

Thank you so much. My bad, I forgot to blur out the email IDs. Thanks for reminding me.
