Hi foamers ,
i'm new in openFOAM, i have to simulate a two phase (water-air) flow through a rotating machinery.
I've started from the bubbleColumn tutorial, imported the mesh from Pointwise and set the CellZone "rotor" with topoSet.
First, i tried to simulate the flow without rotation of impeller, the simulation didn't crash and the results are good.
When i switch on the rotation in the MRFProperties the simulation crashes.
P.S. The turbulence model i've used is the mixtureKEpsion.
Thanks for the attention and i'll be wating your precious suggestions.
