Detailed Description

Mixed-hybrid solution of unsteady Darcy flow.

Standard discretization with time term and sources picewise constant on the element. This leads to violation of the discrete maximum principle for non-acute meshes or to too small timesteps. For simplicial meshes this can be solved by lumping to the edges. See DarcyFlowLMH_Unsteady.
