An Optimal Multigrid Algorithm for the Combining P1-Q1 Finite Element Approximations of Interface Problems Based on Local Anisotropic Fitting Meshes

A new finite element method is proposed for second order elliptic interface problems based on a local anisotropic fitting mixed mesh. The local anisotropic fitting mixed mesh is generated from an interface-unfitted mesh by simply connecting the intersected points of the interface and the underlying...
