Hi, I am new OpenFOAM-2.3.0 user, and I would like to create a free surface application for the OpenFOAM propeller tutorial (pimpleDyMFoam).
I copied all the files into damBreakWithObstacle (interDyMFoam). But I when I tried to run it it didn't work. Can you please help me? Thank you. |

I have this error message:
Code:

You mixed two tutorials. Fro very sure the are thing wihci does not fit. I recommend building your case from one of the tutorials step by step.

Thank you for your advice, I started my case from scratch and followed step by step. But I encountered an error (below) I changed my delta T to 0.001 but the error is still here. Should I increase the delta T ? or is the problem located somewhere else ? Code:
