IternFoam issue during running with mpi

seamanship · May 1, 2024, 06:56

Hello All,

I'm a new OpenFoamer, I'm trying to practise to get used to this software. Unfortunately, while running the solving with interFoam I got the issue as the image below showed, since I lack experience, can anyone here please give me a hint or solution for solving this issue?

PS/ I get this issue after running for a while.

Thank you

The calculation probably diverged. An overflow or underflow occurred somewhere in the calculation.

The cause can be in your settings, say courant number too high. More likely, your grid has some local problem. You can run checkMesh from your case directory and it might give you an indication about your mesh quality.
