Hi Etienne,yes, this is what we do. Can you give more details on why/when this is problematic?Kind regards Bernd On 03/21/2016 10:48 AM, Etienne Ahusborde wrote:Dear DuMuX Community,With my colleagues, we would like to know how Dumux treats the computation of the convective flux at the interface of two heterogeneousmedia for the implicit scheme.It seems that for the absolute permeability, an harmonic mean is used while for the mobility, a weighted upwinding is used (with by default mobilityUpwindWeight_=1 in dumux/imlicit/common/implicitdarcyfluxvariables.hh). We wonder if an other specific treatment is performed since upwinding can produce non-physical solutions.Thanks in advance for precisions.
