[tag] fracture_permeability_parameter

The permeability of fracture is enhanced by \mathbf{K}_f = (1-v)^{\xi}\frac{w^3}{12h_e}(\mathbf{I}-\mathbf{n}\otimes\mathbf{n}) where \xi is the fracture_permeability_parameter which is used to penalize the enhancement of the permeability for the diffused crack regime.

w : The fracture aperture; h_e : The element size; \mathbf{I} : The unit second-oder tensor; \mathbf{n} : The normal vector of fracture.
