Issues with AMR and dynamic load balancing?

Hi everyone!
So I spent a few days on this and can't find a solution. I set up a 3D equivalent of the mutliphaseEuler injection tutorial (/opt/openfoam11/tutorials/multiphaseEuler/injection). In this case I want to test adaptive mesh refinement using the alpha.air field and the dynamic load balancing. However i run in the following issue: - Running the case in parallel on 8 processors with AMR works fine - Running the case introducing dynamic load balancing works until the mesh is refined the first time. At that point, when the dynamic load balancing step begins, the solver hangs with 8 processors at 100% and the rest idle. I attach the case folder, any help would be appreciated! The harware I am running on is: 2x intel XEON E5-2670 12 core 64GB RAM |
