Air flow through Roots kompressor - rotating rotors problem

I want to make a air flow simulation through Roots kompressor, but I face a problem which i cant solve. I choose the rotating regions and boundary contitions and everythinfg seems ok. But while I want to solve the simulation there is an error:

Mesh generation started20:35:30 , Dec 01
Warning! Unable to resolve the local rotating region20:35:43 , Dec 01
Mesh generation terminated20:35:44 , Dec 01

The geometry of a Roots kompressor causes that the rotating regions of the lobes overlap. Is it possilbe to solve such a simulation?
