Dear Foamers
I am simulating a radial inflow turbine bassage with cyclic BC on periodic surfaces and overlapGgi at interface between Upstream and impeller and impeller and downstream. BC and initial values are attached. Rotational speed is 2303.1833 RPS. I am using transonicMRFDyMFoam. When I run the case I am getting the following error. What could be the Problem. Please guide me. Code:
