WebOct 11, 2024 · For high contrast porous media, more than one degree of freedom should be introduced for accurate approximation of the processes. The main idea of GMsFEM is to apply multiscale basis functions to obtain important information in each coarse grid (com- putational grid) and build a reduced-order model. WebGMsFEM has been studied for a various applications related to flow problems (see [5, 7, 4, 9, 8]). In GMsFEM, we solve equation (1) on a coarse grid where each coarse grid consists of a union of fine-grid blocks. In particular, we design (1) a snapshot space (2) an offline space for each coarse patch. The offline space consists of handbook services directive
