[Libmesh-users] Neumann and Robin bcs with FemSystem

[<mar...@ge...>]

Hi all,

When using the FemSystem class, what is the best way to implement
Neumann and Robin boundary conditions? Is this still by adding penalty
terms to matrix and RHS? 

If yes, does this collide with using the DirichletBoundary class (I
think it shouldn't)? Or should all bcs be enforced with penalties?

Thanks for any hints.

Martin
