Compressible Finite Volume HLLC Boundary Conditions

Does the CNSFVHLLC class have a no-slip boundary condition? In the Incompressible finite volume, I see there is a no-slip wall BC, but I am not sure which of the CNSFVHLLC boundary conditions would mimic that.

Hello

I dont think so. @lindsayad
No slip boundary conditions are more of a viscous flow concept, and the HLLC solver is for Eulerian flows with 0 viscosity.
If you have a reference for their formulation for HLLC we could have a look

We have this example here of using our fully compressible Kurganov-Tadmor implementation in a cavity with viscous drag from the walls. Use of the FVOrthogonalBoundaryDiffusion objects ensures that the only momentum flux at the walls is due to viscous forces (no advective outflow of momentum).

Thank you. I will look at this right away.

Note that a KT boundary condition may not mix well with HLLC kernels. I'd recommend switching over completely from HLLC to KT for this application.

That example does not use any boundary conditions unique to KT
