Abstract:
For the solution of practical flow problems in arbitrarily
shaped domains, simple Schwarz domain decomposition methods with
minimal overlap are quite efficient, provided Krylov subspace methods, such as the
GMRES method, are used
to accelerate convergence.
With accurate subdomain solution,
the amount of time spent in solving these problems may be quite large.
To reduce computing time,
inaccurate solution of subdomain problems is considered, which requires a
different, GCR based, acceleration technique.
Much emphasis is put on the multiplicative
domain decomposition algorithm since we also want an algorithm which is
fast on a single processor.
Nevertheless, the prospects for parallel implementation are also
investigated.
