Dear Foamers,

Greetings!!

In my current case, I am running a dynamic mesh using interFoam solver. The mesh consists of :
1. Reactor (cylindrical)
2. Rotating blade
3. AMI & AMI slave

I get the following error when I run the simulation.

Please let me know what is causing this error and how to remove it.

Kind regards and Thanks in advance

Most probably it is an initial and/or boundary condition. You have a mathematical operation which is illegal like division by zero which OpenFOAM will complain. Can you share the test case. I work with topoChanging mesh with Solver interDyMFoam but not AMI. Would love to check out the case.
