Hi everybody,
I'm studying Mechanical Engineering at Politecnico di Bari (Italy). I'm writing a thesis analyzing incompressible flow over an airfoil.

First I launched an analysis and it worked, but I wasn't satisfied with the precision of the results. So I replaced the mesh (made in Pointwise) with a finer one on the same geometry.

When I launched the analysis again it aborted because of this error:

Starting time loop

Floating point exception

Can anyone help me please? (If you need any of the case files, please ask me.)

I suppose you are using a turbulence model, so maybe there is a problem with your boundary and initial conditions. Could you please upload your case or your 0 folder to see whats happening?

Are you running in parallel?

In the meanwhile I solve this problem replacing the mesh. Maybe there was a mistake.

Thank you for your answer.
