moving mesh problem
 
Has anyone done a moving mesh analysis with both translation and rotation? for o-type mesh i used the bcs pressure, symmetry and moving wall for which i supply a user defined subroutine everything seems ok but when i start simulation the solution diverges.. any ideas why it is so?

Look into the pressure under relaxation factor. Typically it should be aroung 0.8 for such problems. Default is 1.
