Abstract We propose a quality-based optimization strategy to reduce the total number of degrees freedom associated with discrete problem defined over polygonal tessellation Virtual Element Method. The presented Quality Agglomeration algorithm relies only on geometrical properties mesh, agglomerating groups neighboring elements. test this approach in context fractured porous media, which generat...

The multiscale hybrid mixed finite element method (MHM-H(div)), previously developed for Darcy’s problems, is extended coupled flow/pressure and transport system of two-phase flow equations on heterogeneous media under the effect gravitational segregation. It combined with an implicit solver in a sequential fully (SFI) manner. MHM-H(div) designed to cope complex geometry inherent nature phenome...
