[Nek5000-users] Moving Wall Advice

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

Paul, Oana -- thanks for the tips.

The ocyl example seems very close to what I need.   

One question: Will the ALE formulation as currently implemented work if I'm solving a 2D axisymmetric-flow problem (where the temperature is used to represent the azimuthal flow component)?

Thanks again,
Mike

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).
