Modelling a Gerotor Pump
 

Hi, im doing a project which involves designing a gerotor pump for a company. Iv had previous experience using fluent concerning external aerodynamic flows, droplet simulations and melting/solidification problems. However, I have no experience using dynamic meshing or moving and rotating parts such as this.

For an idea of my problem here is an example which is pretty much the same: www.fluent.com/solutions/automotive/ex238.pdf

I was wondering if anyone could give me an idea of how to mesh and set up a 2.5D problem using fluent and gambit. If there are any simpler ways of modelling this situation then I would like to know. I'm only after approximate values so the mesh does not need to be especially fine.

Thank you.
