Numerical approximation of internal discontinuity interface problems
journal contribution
posted on 2015-09-11, 12:53 authored by Marco DiscacciatiMarco Discacciati, Alfio Quarteroni, Samuel QuinodozThis work focuses on the finite element discretization of boundary value problems whose solution features either a discontinuity or a discontinuous conormal derivative across an interface inside the computational domain. The interface is characterized via a level set function. The discontinuities are accounted for by using suitable extension operators whose numerical implementation requires a very low computational effort. After carrying out the error analysis, numerical results to validate our approach are presented in one, two, and three dimensions.
