โœฆ Synopsis

A class of indeยฎnite overlapping Schwarz methods is introduced and studied for time-dependent Stokes problems, discretized with either mixed ยฎnite elements or mixed spectral elements. The methods proposed are based on the solution of local time-dependent Stokes problems on overlapping subdomains and on the solution of a coarse time-dependent Stokes problem deยฎned on the coarse subdomain mesh. The resulting preconditioner is accelerated by an appropriate Krylov space method, producing a very ecient, scalable and parallel solver.

Three domain decomposition methods for saddle point problems are introduced and compared. The first two are blockdiagonal and block-triangular preconditioners with diagonal blocks approximated by an overlapping Schwarz technique with positive definite local and coarse problems. The third is an overl
