Abstract
In this paper, we present a generalization of a Neumann-Neumann domain deco mposition method with scalability properties to solve non-symmetric systems . This generalization uses the theoretical framework of Schwarz additive de composition method,vith introduction of a coarse space well adapted to non- symmetric cases. The efficiency of this method is evaluated on non-symmetri c frictional contact problems. (C) 2000 Academie des sciences/Editions scie ntifiques et medicales Elsevier SAS.
