The boundary condition rotatingWallVelocity does not have a relative option? Hence this shouldn't do anything. Please try renaming yes to banana und run the code. This shouldn't stop the solver and...

You could use arbitrary mesh interfaces AMI and rotate the mesh using solidBodyMotion. This makes the meshing process a bit more intricate, but you can define different motion zones moving relative...
