Rotating Geometry
 

Dear Foamers,

I'm currently fighting with my cooling duct geometry to make it rotate.

I know there are posts about this subject but none answer or give hint to my problem.
I'm sure people who have already used SRFSimpleFoam or MRFSimpleFoam can answer my question...

What I want is my whole geometry to rotate about an axis of rotation at a constant speed. This is quite simple and I'm sure there is a way to make this but I can't find one example or tutorial showing how to do this. I've struggled with the solver but keep having completely weard solutions; I'm using lauder-sharma k-eps low-re turbulent model (RANS) and I know it's not the best suited for rotating geometries but still it should give more or less physical solutions.

So can someone tell me how to do this?

I've theses patches :

inlet
fixedWalls
outlet

It's a 3D geometry. It works with simpleFoam. My rotation axis is at (0 -1 0) for its origing and is around z. My mesh center is at (0 0 0) so the axis of rotation is below it.

Thanks for your help
Regards
