Experiences with Advanced CFD Algorithms on NEC SX-4

In this paper three topics related to parallel CFD simulations are discussed. The first topic is the shared memory parallelization of the unstructured adaptive flow solver Hexadap. The second topic discusses the performance results of this parallelization on a 16 processor NEC SX-4. The third topic combines the first two and concerns the CFD working environment ISNaS as developed by the National Aerospace Laboratory NLR.
