Unexpected error when changing inlet velocity

Hi Foamers.
I am trying to simulate a ship propeller in different inlet speed. So far I was able to complete the simulation in a specific velocity (5.4 m/s to be exact). But when I change the inlet velocity to a lower value (and I change nothing else) for example 2.7 m/s , the solver (pimpleDyMFoam) diverges after 2 or 3 time-steps. Does anyone have any idea why this happens? |
