At the German Aerospace Center, the parallel simulation systems TAU and TRACE have been developed for the aerodynamic design of aircrafts or turbines for jet engines. For the parallel iterative solution of large, sparse equation systems within both CFD solvers, block-local preconditioners are compared with global block Distributed Schur Complement preconditioning methods for real or complex matrix problems. Performance results of preconditioned FGMRes algorithms are presented for TAU and TRACE problems on many-core systems.
