An experimental study of interface relaxation methods for composite elliptic differential equations

Abstract

The recently proposed simulation framework of interface relaxation for developing multi-domain multi-physics simulation engines is considered. An experimental study of the behavior of two representative interface relaxation methods is presented. Three linear and one non-linear elliptic two-dimensional PDE problems are considered and they are coupled with both cartesian and general decompositions. The characteristics and the effectiveness of the proposed collaborative PDE solving framework in general, and of the two interface relaxation methods in particular are shown. (c) 2007 Elsevier Inc.
