Multiscale extended finite element method for deformable fractured porous media
Journal of Computational Physics(2021)
Abstract
•Multiscale Extended Finite Element method (MS-XFEM) is developed.•Discontinuities are involved only in the multiscale basis functions.•MS-XFEM contains no additional degrees of freedom in the coarse-scale system.•MS-XFEM is directly applicable to heterogeneous highly fractured problems.•MS-XFEM develops an efficient and accurate simulation framework.
