At the Institute for Propulsion Technology of the German Aerospace Center (DLR), the parallel simulation system TRACE (Turbo-machinery Research Aerodynamic Computational Environment) has been developed specifically for the calculation of internal turbo-machinery flows. The finite volume method with block-structured grids requires the parallel, iterative solution of large, sparse non-symmetric systems of linear equations. For convergence acceleration of the underlying FGMRES or BiCGstab iteration, parallel preconditioning based on the distributed Schur complement method has been applied. Numerical and performance results of this approach will be presented for typical TRACE problems on parallel computer systems, including multi-core architectures.
