Hi All,
I'm trying to solve a fluid dynamics problem with modified icoFoam (see attached). Found that different processor running give me very different results. Both solver and cases are attached, please give me any suggestions on what happened. Thank you all in advanced!

Do you mean that you have different results if you run you case on 1 or n processors ?
