Couple FE and FV variables at interfaces #24308

Open pbehne opened 1 year ago

pbehne commented 1 year ago

Reason

To couple finite element variables (solids) to finite volume variables (fluids) at an interface.

Design

The coupling could occur in the FVInterfaceKernels block, when interface conditions are defined.

Impact

The only currently known way of coupling is through the multiapp/transfer system, which requires iteration to converge the interface condition.

@lindsayad Would the work in #18394 also be useful here? That wasn't for interface kernels, but I imagine it would share some infrastructure.

Maybe. We may also just be able to use the functor system
