Abstract

Two mesh generators embedded in the GeRa code for the solution of groundwater flow and radionuclide transport problems are discussed. The first one is a triangular-prismatic generator with the ability of cell degeneration; the second one is the polyhedral octree mesh generator implementing the cut-cell technology. These generators allow the user to automatically create conformal polyhedral adaptive grids in three-dimensional geological domains with consideration of complex boundaries, top and bottom geological layer surfaces, pinch-outs, and geological heterogeneities.
