Hello im beginner with OpenFOAM and im trying to run a stirred tank in a multiphase system with twoPhaseEulerFoam solver and MRF, but after some minutes running i got the next text:

Max Ur Courant Number = 1010.77

Excepción de coma flotante (`core' generado)

I don't understand where is the pŕoblem.

Kind regards.
