Hi Samuel,
which DuMuX version do you use? For DuMuX 2.12, I can send you some code.
Best regards,
Martin

Hi Samuel,
years ago there was an implentation of a so called "fluxline". This
method worked for the box-discretization and was exact (based on the
variables of the final newton step) and worked inside the domain. The
flux computation on/over boundaries is more complex if you use no weak
impossition. So you may use a fluxline in combination with a mass
balance at the boundary scvs.
I've always used the fluxline to ensure that my modells and
developments are mass conservative and correct. Further it is
important to know and compare fluxes in real world applications.
Best regards,
Leo
