Hello friends
I am trying simulation single phase scrubber using simpleFOAM. I did geometry and meshing using gambit. During the solving I found the error of sigFPE [0] #0 Foam::error:  rintStack(Foam::Ostream&) at ??:?[0] #1 Foam::sigFpe::sigHandler(int) at ??:?

Check your mesh, it seems the solver failed due to failure in mesh. Check mesh quality by running the following command (in terminal): checkMesh Try correcting skewed cells - Best Luck! |
