A coupling interface method for elliptic interface problems
We propose a coupling interface method (CIM) under Cartesian grid for solving elliptic complex interface problems in arbitrary dimensions, where the coefficients, the source terms, and the solutions may be discontinuous or singular across the interfaces. It consists of a first-order version (CIM1) and a second-order version (CIM2). In one dimension, the CIM1 is derived from a linear approximati...

متن کاملMIB Galerkin method for elliptic interface problems
Material interfaces are omnipresent in the real-world structures and devices. Mathematical modeling of material interfaces often leads to elliptic partial differential equations (PDEs) with discontinuous coefficients and singular sources, which are commonly called elliptic interface problems. The development of high-order numerical schemes for elliptic interface problems has become a well defin...
متن کاملA sharp interface finite volume method for elliptic equations on Cartesian grids
We present a second order sharp interface finite volume method for the solution of the three-dimensional elliptic equation ∇ pβp~xq∇up~xqq fp~xq with variable coefficients on Cartesian grids. In particular, we focus on interface problems with discontinuities in the coefficient, the source term, the solution, and the fluxes across the interface. The method uses standard piecewiese trilinear fini...
متن کاملAdaptive Mesh Refinement for Elliptic Interface Problems Using the Non-conforming Immersed Finite Element Method
In this paper, an adaptive mesh refinement technique is developed and analyzed for the non-conforming immersed finite element (IFE) method proposed in [27]. The IFE method was developed for solving the second order elliptic boundary value problem with interfaces across which the coefficient may be discontinuous. The IFE method was based on a triangulation that does not need to fit the interface...
