Description
In the decoupled finite volume models Dirichlet boundary conditions are implemented as kind of solution dependent flux boundary conditions. The fluxes result from the gradient of a given boundary pressure and the current pressure in a boundary cell.
In my opinion there are two reasons to implement such a boundary implementation as an alternative to the current Dirichlet implementation for the fully implicit models:
1) In case of heterogeneous porous media implicit and decoupled models can be compared (better/at all?)
2) It leads to a better solution behavior with regard to physics as well as with regard to stability at heterogeneous Dirichlet boundaries
