The module provides discretization methods for three different equations:
Examples of usage for the three options can be found in mpfa_ex, mpsa_ex, and biot_ex, respectively, see the examples folder. The code has been tested for 2D and 3D problems on Cartesian and simplex grids, see papers below for illustrations.
This implementation uses the weakly symmetric formulation used in  (specifically using vertex-based averaging).
Further information on the methods implemented herein, in particular the discretization of elasticity and poro-mechanics, can be found in the following papers (all open access)
