Error estimates for a mixed finite element discretization of some degenerate parabolic equations
Error estimates for a mixed finite element discretization of some degenerate parabolic equations
We consider a numerical scheme for a class of degenerate parabolic equations, including both slow and fast diffusion cases. A particular example in this sense is the Richards equation modeling the flow in porous media. The numerical scheme is based on the mixed finite element method (MFEM) in space, and …
