A finite element method for high-contrast interface problems with error estimates independent of contrast

Numerical Analysis 2016-10-18 v3

Abstract

We define a new finite element method for a steady state elliptic problem with discontinuous diffusion coefficients where the meshes are not aligned with the interface. We prove optimal error estimates in the L2L^2 norm and H1H^1 weighted semi-norm independent of the contrast between the coefficients. Numerical experiments validating our theoretical findings are provided.
