Hi guys,

I am trying to simulate a channelFlow at Re=5000 with rhoPimpleFoam.
Problem is my simulation crashes immediately:

Create time

Create mesh for time = 0


PIMPLE: no residual control data found. Calculations will employ 10 corrector loops

You can find my inlet conditions in the attachement

Where is the problem?

Thanks in advance!

you devide by zero, and I guess your initial zero pressure field is the reason.

yes that was the reason, thank you!
