Hi there, I’m trying to run an FSI simulation using OpenFOAM for the fluid and CalculiX for the solid, but for some reason my simulation consistently stops running at time window number 101 without any error message indicating why. I have tried two different sizes of timestep (0.001s and 0.005s) an…

Simulation gets stuck at same time window

Solved it at last! Increasing the end time in CalculiX didn’t help, but setting INC to a very large number (I put INC=1000000) after *STEP in the input file did.

Thanks for helping me with this!
