Claim Text:
1. A computer-implemented method of modeling a hydraulically driven fracture comprising: selecting an enrichment region for modeling a subject hydraulically driven fracture, the enrichment region representing a permeable medium, and the modeling resulting in a model of the subject hydraulically driven fracture; defining respective positions of a first set of nodes and a second set of nodes in the enrichment region, wherein the second set of nodes are superposed on the first set of nodes; performing a coupled pore fluid diffusion and stress analysis on the enrichment region at the first set of nodes; determining whether the second set of nodes is activated as a result of the coupled pore fluid diffusion and stress analysis; computing solutions to one or more equilibrium equations, the one or more equilibrium equations based on whether the second set of nodes is activated as a result of the coupled pore fluid diffusion and stress analysis, wherein the one or more equilibrium equations define tangential fluid flow and normal fluid flow in the model of the subject hydraulically driven fracture; and visually outputting to a user a rendering of the model of the subject hydraulically driven fracture.
