A combined multiscale finite element method based on the LOD technique for the multiscale elliptic problems with singularities
Kuokuo Zhang, Weibing Deng, Haijun Wu
In this paper, we construct a combined multiscale finite element method (MsFEM) using the Local Orthogonal Decomposition (LOD) technique to solve the multiscale problems which may…
