Hi,

I need to run unsteady incompressible flow in pisoFoam. Since my soln was blowing up, I wanted to start from steady state soln and i turned towards potentialFoam.

I get floating point exception error when running potentialFoam.
Code:
[sudarsan@nebula run]$ potentialFoam

Floating point exception
my mesh has got non-orthogonality issues. I am attaching the case here.
can somebody help me ?
