What this MR does / why does DuMux need it: This MR implements new coupling conditions for stokes-darcy interfaces, as proposed/described by Elissa Eggenweiler. The new interface conditions are meant to be more general and appropriate in comparison to the Beavers-Joseph condition and the current normal momentum coupling.
TODO:
-
Combine new/standardPorousMediumVelocity, beaversJoseph/nTangentialVelocity and old/newMomentumCouplingCondition -
Allow unsymmetrizedStressTensorForBJ and unsymmetrizedStressTensorForIC! -
Set up two tests: Beaver-Josephs and newIC, see: dumux/test/multidomain/boundary/stokesdarcy/1p_1p, @Elissa -
Check deprecation and documentation, link to paper from Elissa? -
Add warning for newIC with symmetrized tensor -
Folder and file names should not contain capital letters. -
Follow styleguide: Correct indent, curly braces -
