HYDRAULIC FRACTURE SIMULATION WITH EXTENDED FINITE ELEMENT METHOD

摘要

PROBLEM TO BE SOLVED: To simulate a hydraulic fracture in rocks and to model a fluid flow in the life sciences.SOLUTION: A computer-implemented method includes defining respective positions of a first set of nodes and a second set of nodes in an enrichment region, and performing a coupled pore fluid diffusion and stress analysis on the enrichment region at the first set of nodes. It is then determined whether the second set of nodes is activated, which represents a fracture, as a result of the analysis, and the results are visually output to a user.
