[Nek5000-users] Moving Wall Advice

[nek5000-users at lists.mcs.anl.gov]

Hello Neks,

I'm trying to simulate a flow where one of the boundaries is moving in a manner that requires the mesh to deform as a function of time.   In short, the conditions of the flow will determine how the boundary moves (it's a fluid-structure interaction problem, but the structure is a rigid body suspended in the fluid).

Are there any available examples that would provide guidance?

If not, does anyone out there want to share some wisdom?  For example, I understand that I will need IFMVBD = True, and I will need "mv" boundary conditions specified in the .rea file, but in which routine should I modify the mesh node locations and velocities?

I found a similar question in the archive under the subject "what parameters for a moving wall induced velocity problem?" but there didn't seem to be any follow-up responses.

Thanks in advance.

Cheers,
Mike
