The non-linear tpfa and mpfa discretizations should be equivalent for K-orthogonal grids. A test for this case is required.

This is the suggested sketch for the test:

Project a strong solution of a nonlinear boundary value scalar problem with Dirichlet boundary conditions to obtain the projected approximation p_h
Employ p_h to evaluate the pair (Jac(p_h), Res(p_h))_xpfa where x = {t,m}
Make the assertion (Jac(p_h), Res(p_h))_tpfa is numerically close to (Jac(p_h), Res(p_h))_mpfa

Failure of this test indicates an inconsistency in the non-linear implementation of mpfa.
