 This solver computes the vertical distance from a surface (either free surface or bedrock in Glaciology). In structured FD-grids this is a trivial procedure - not so in unstructured FEM meshes as used by Elmer. A degenerated Poisson equation has to be solved in order to get nodal values for either the flow depth below the free surface or the flow height above the bedrock. It can also compute the horizontal derivative of the upper/lower surface if ''Depth''/''height'' is calculated. This solver computes the vertical distance from a surface (either free surface or bedrock in Glaciology).
