Structured Grid Solvers II - Parallelization of Block Structured FLOW Solver

This paper reviews some general considerations on the parallelization of large block structured flow solvers for production use. Parallelization is therefore not treated as an isolated subject of research, but as a tool to increase the computational power for the user and as integral part of the development environment of a CFD code. As an example the parallelization of the FLOWer code using the portable communications library CLIC-3D is given. Results of benchmark tests obtained on various computer hardware architectures demonstrate today's possibilities of parallel processing in CFD applications.
