Hello people

I am trying to learn how to implement AMI with the help of pimpleDyMFoam tutorial of propeller. when I start the simulation using Allrun command the simulation blows up after ~35 iterations. the continuity suddenly becomes from 0.1 to 1e+3 and then the simulation diverges. I have not done any changes to the tutorial provided with the distribution (I am using OF 2.1.1).
I am quite confused why that is happening. Any suggestions what should be done ?

Also I want to implement AMI with MRFSimpleFoam. Do we need constant/dynamicMeshDict ... ? Also what else will be the major changes when compared to the tutorial of propeller. Because tutorial is a transient simulation with pimpleDyMFoam where as I want to do steady state simulation.

Any help/suggestions will be greatly helpful and will be appreciated.

Thanks in Advance.

Hello,.
In MRF we don't use the dynamicsMeshDict, but we need MRFProperties, it's different scripts. then you have to change some scripts.
