Hi,

i have a problem with my project. I want to simulate my geometry in CFX. Since one Domain is moving i want to do the CFX Workbench-Remeshing feature, so the mesh will be remeshed when there are bad orthogonality angles. I am running the remeshing script with opening the workbench in batch mode while cfx solver. The Mesh will be remeshed with better elements, but somehow i always get an offset of the geometry after each remeshing step. These offsets are deflecting the motion i wanted.

I tried several times to find the error, but i couldnt find it yet.

I have uploaded the video animation of a run without remeshing (reflecting the motion i want) and a run with remeshing (offsets occuring after each remeshing step). U can download them here:
