pimpleDyMFoam  GGI  dynamicMeshDict
Hi everyone,
I am working on a centrifugal pump simulation. I already managed to run it with MRFSimpleFoam (steady state), and now i need to run it transient. In the pump mesh, i have the rotating part (rotor) impeller, and the stationary part(stator) spiral and the ggi faces between rotor and stator. I took a look at the propeller tutorial, and tried to implement the necessary changes in the pump, but i am getting an floating point exception. I took the first time step from my steady state solution. The error message is as followed: Time = 1.0000023 From function void GGIInterpolation<MasterPatch, SlavePatch>::rescaleWeightingFactors() const in file /opt/net/OpenFOAM/OpenFOAM1.6ext/src/OpenFOAM/lnInclude/GGIInterpolationWeights.C at line 544 Uncovered faces found.

Can anyone give me a hint how to set my dynamicMeshDict file? thanks in advance
