Methods for approximating discontinuous or rapidly changing conductivity in numerical calculations

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Numerical methods for dealing with a temperature dependent conductivity are discussed. An approach based on a local application of a Kirchhoff transformation at the discrete level is presented. The application of this transformation - that does not require any inversion- is demonstrated on solving a two-dimensional test problem.
