Hello everybody,


currently I am working on a simulation with a moving block. After this block follows another not moving block. Both blocks are connected by the cyclicPeriodicAMI patch.

Now I noticed that rhoPimpleDyMFoam needs 10 times more time to calculate a time step than rhoPimpleFoam.

Does anyone have any experience with this and could give me some tips? I also noticed that most of the time is needed to "map" the patches and that additional processors do not increase performance.

Best regards
MNoCeZ
