Accuracy analysis of structure with nearby interfaces within XFEM

AIP Advances, 2017
This paper presents the fundamental principle of the extended finite element method (XFEM) for electromagnetic field analysis. The accuracy analysis of structure with nearby interfaces within XFEM is presented. A numerical example applied to the parallel

Multiscale Simulation of 2D Heat Transfer in Composite Media Based on Global–Local Enrichment Functions

Mathematics
In this study, the extended finite element method (XFEM) was integrated into the generalized multiscale finite element method with global–local enrichment (GFEMgl) to simulate 2D heat conduction in highly heterogeneous materials (i.e., matrixes with ...
