Comparison Between Mimetic and Two-Point Flux-Approximation Schemes on PEBI-grids
Thomas Lunde · NORA - Norwegian Open Research Archives · 2007
Two discretizations of the flow equation for flow in porous media are presented and compared: the mimetic finite-differences method and two-point flux-approximation volume method. Theory and implementation of a layered PEBI-grid (Voronoi-grid) generator are presented. The two discretizations are compared through numerical experiments on PEBI-grid.
