A non-conforming finite difference discrete fracture model based on an energy principle
Ziyao Xu
We propose a finite difference discrete fracture model for single-phase flow in fractured porous media. The method is derived from a unified energy principle and is implemented on…

An unfitted finite element discrete fracture model for low-permeability barriers via local stiffness matrix modification
Ziyao Xu
Finite element methods are among the most widely used discretizations for flow in porous media, and their discrete fracture models (DFMs) for highly conductive fractures are well-e…
