Panzer: Non-conformal periodic boundary conditions

[saveryrc]

Question

This Issue relates to a CFD package simulating a 2d or 3d channel where the inlet and outlet planes are prescribed as periodic boundary conditions. We would like to have the capability to use non-conforming nodes on each of these planes so that mesh refinement can be done without having to match node pairs/refinement beforehand.

Does Panzer have this interpolation capability or a native implementation to handle non-conforming periodic boundary conditions?

Thanks,
Ryan

There is nothing automated to handle your use case at this point. Panzer does have an L2 projection capability to map DOF values across bases, but this would have to be modified for use with sidesets - it currently is used for element blocks.
