Divergence problem running a DFBI
 

I'm trying to simulate the behaviour of a propeller thrusted airplane using Superposed Rotation. My geometry is composed by sub domain containing a propeller and a main domain containing the aircraft and this sub-domain. The reason for the sub domain is that the mesher doesn't have to re-do the mesh for every rotation in all the space but only in the sub-domain containing the propeller. The problem i encounter is that my simulation diverge. Someone can help? thanks in advance

additional info
the propeller is rotating at 10000 rpm and time step is 1 x e-04
