This way we can formulate the flux dependent on both the matrix as well as the facet permeability. This significantly reduces the condition number of the resulting matrix and thus improves newton convergence.
On 3d grids, the maximum value of 8-bit integer types can easily be surpassed for the local indices within interaction volumes. We use the larger local index type now. This way we should always be on the safe side.
The coupling residual of a low-dim element is independent with respect to which bulk dof it is evaluated. We therefore provide an index-independent interface as well.
The interaction volume-local system solve should be identical among many different mpfa schemes. We therefore put this into the mpfa-scheme-agnostic helper class where it can be reused in other schemes.
