【 摘 要 】

We present a procedure to generate bipartite grids for simply connected domains in 2-D and 3-D, of prescribed size and controlled regularity elements.The mesh elements K of the triangulation satisfy ζK ≤ C, where ζK is the regularity and C is a constant depending on the shape parameters of the initialmesh. Bipartite grids permit a well-posed mixed-mixed variational formulation of problems, such as the porous media flow equation and other linearphysical phenomena, as well as Galerkin-type discontinuous relaxations.
