Good evening.

I am trying to create a rotor stator system wit flotation cell. i am using something similar to a outokumpu impeller. a rotating set of blades inside a diffuser. in Gambit, i have done to scenario's , i have made 2 volumes, with one common cylindrical face, (one rotating inside the other), and 2 volumes with 2 common cylindrical faces ( one overlaps the other). the interface of these cylinders sits inbetween blades and diffuser within the fluid zone not on the solid.

Howver i cant seem to get this to work in Fluent, i have read all the manuals. does any body have any insight on this topic?

What type of error does Fluent show you? What type of MRF are you using, sliding mesh, mixing plane? Cheers, Javier

I am using sliding mesh, if i use the way of two volumes with 2 interface faces over lapping i get a nopositive volume exists message, and if i use the two volumes split in two - i just get either Fatal error - or simply Divergance detected before any iterations occur.
