Hello,
I successfully ran the elastic-tube-3D tutorial on my local machine using OpenFOAM v2412, and the simulation proceeded without any issues. However, when I attempt the same simulation on a Compute Canada cluster, where the latest available version is OpenFOAM v2406, the OpenFOAM solver diverges early in the simulation. Specifically, I encounter exploding pressure residuals and eventually a floating-point exception related to mesh motion. No changes were made to the tutorial configuration files.
Do you know which older versions of OpenFOAM (e.g., v2206, v12, etc.) are known to work reliably with this FSI configuration?
Additionally, while I am able to run the coupled simulation using sbatch, it currently only works in serial mode. I can’t run the simulation in parallel on the cluster, even with decomposePar and mpirun. Could you suggest the correct approach or example scripts for running the full FSI case in parallel (both solid and fluid) using sbatch?
Thank you for your support.
