An Adapted Coarse Space for Balancing Domain Decomposition Methods in Nonlinear Elastodynamics

Abstract

This work is devoted to a scalable domain decomposition method to solve nonlinear elastodynamic problems. Large nonlinear elastodynamic problems represent an appropriate application field for substructuring methods which are efficient on parallel computer with the proviso of using specific preconditioner techniques well adapted to the mechanical modeling. Accordingly, we develop an adapted balancing domain decomposition method [4, 6] appropriate for solving this kind of systems.
