Hello everyone,

I'm new to OpenFOAM and I ran some simple cases using simpleFoam. Now I want to move to rotating reference frame. So I ran three cases separately in simpleFoam, SRFSimpleFoam and MRFSimpleFoam. However, the results from simpleFoam and SRFSimpleFoam are exactly the same, but they are different from the result from MRFSimpleFoam. I don't know why. I think they three should be exactly the same. And I attached these cases in the attachment. Maybe I setup the model in a wrong way. Please give me a hand. Thank you so much.
