solid mesh motion, inlets, MRF?

newbie_cfd · August 13, 2015, 00:04

Hello,

I'm investigating an oscillating foil (up and down), large movements so I can't use mesh morphing. I'd therefore like to move the complete mesh.
Reading through the forum, several people have asked questions that are similar; but there hasn't been any answers.
My main 'concern' is the treatment of the inlet and outlet boundaries, from what I've seen, moving the mesh (dynamically in the solver) is not too much but what happens to the boundaries? will it be handled properly or should they be defined as unsteady boundaries?
Would an MRF approach help? But here again, what I have been is mainly about internal flow, so mention of inlet/outlet boundaries treatment.

Any clues/help would be greatly appreciated.

Thanks,
Nija.

Anybody?
I guess it's not currently possible to do such things?
