Sliding Mesh

Sridhar

Dear Fluent Users,

My work (study of flow behavior under a lawnmower deck, with three cutting blades) focuses on transient flow behavior in a multiple reference frame; I believe that I need to use sliding mesh technique to analyze the problem. How should I mesh the system in Gambit in order to define sliding mesh boundary conditions in Fluent? Do I need to separately mesh the virtual cylindrical regions surrounding the blades and the remaining part of the mower deck? I am very much confused how to approach this type of problem. The Fluent tutorial on sliding mesh has two different mesh files and they are merged using Tmerge, How can one create two different mesh files from same geometry? I would really appreciate if anyone can explain me how to approach this problem.

Thanks.

Sridhar.
