»Numerical upscaling of perturbed diffusion problems«

Abstract:
In this talk we consider elliptic partial differential equations with rapidly varying diffusion. In particular we study efficient solution techniques for problems where the diffusion is perturbed from a reference configuration. The goal is to develop an efficient numerical method for solving multiple perturbed problems by reusing local fine-scale computations. The proposed method is based on the Petrov–Galerkin Localized Orthogonal Decomposition (PG-LOD) method which is a generalized finite element method with multiscale shape functions in the trial space. We focus on several types of perturbations, present results of the numerical analysis and show numerical experiments.
