How do i specify my boundary conditions in GAMBIT when i am intending to use MFR in FLUENT?

I had to two blocks(inner & outer). The inner contains the impeller & shaft and it is rotating one while the outer is the stationary which contains the baffles. I specifed my blades & shaft as moving wall with relative velocity adjacent to zone as zero. There is an interface which i created but my solution is not converging. I guess it is my boundary conditions or creation of the outer or inner blocks.

I need help.

There are two points you can check:

Is your grid ok after you set the interfaces? You can check this with the command grid -> check.

The MRF is more suitable to problems with small rotor/stator interaction. You can try to use sliding mesh if your interaction is strong.

Good luck

There is a Fluent tutorial on how to set a sliding mesh problem. If you have access to the www.fluentusers.com, the URL is http://learningcfd.com/login/fluent/...iding-mesh.pdf

If not, I can send you the file via email.

I think it is enough to you to set your problem properly.
