-------------------
The flux reconstruction is a projection of the fluxes used in the Discontinuous Galerkin method into a vector field function. Using correct elements, this procedure can ensure that fluxes in normal direction to the element are *equivalent* to those computed by the Discontinuous Galerkin method, and most importantly, it can also ensure the continuity of them. Hence, the resulting vector field is useful to compute other problems that rely on the fluxes of the water (i.e. solute transport).
The flux reconstruction technique always use Raviar Thomas finite elements of one degree less than the one set for the Richards model. Flux reconstruction is not available for non-conforming grids (i.e. Cube-adaptive grids).
The flux reconstruction technique always use Raviar Thomas finite elements of one degree less than the one set for the Richards model. It can be identified in the vtk file by the name ``flux_RT{k-1}``, where ``k`` is the finite element order set for the Richards model. Flux reconstruction is not available for non-conforming grids (i.e. Cube-adaptive grids).
