Dear DuMuX experts, Please advise what is the best way to assign variable fracture aperture for a multidomain/fracture flow application.
I would like to have apertures be pre-computed and read by DuMuX from an external file, so that the fracture apertures correspond to the numbering of fracture elements in the gmsh mesh file. Currently the apertures are read via extrusionAtPos(const GlobalPosition& globalPos) in the fractureproblem.hh. It would be great if I could get not the position of the element's center as parameter, but say the corresponding SubControlVolume which apparently does have the elementIndex. But how can I do this without modifying dumux/common/fvproblem.hh ? Thanks, Nikolai
