Hi, I am trying to solve the momentum equation. The 1st time step was ok, but at the 2nd, the error message is:
Petsc has generated inconsistent data - Divide by zero! What does it mean? Do you know what is the likely cause of the error? I did not find an unusually large values in matrix and RHS vector. Thank you very much. -- Yours sincerely, TAY wee-beng
