Abstract:

Viscous/inviscid aerodynamics equations are solved through a parallel try for the classical Beam Warming implicit solver. The program mode SPMD is selected, and a static non overlapped decomposition method is used to establish the projection between the computation domain and the processing nodes of parallel systems. The results show that the stability and convergence of the original serial algorithm is maintained and that the speed up and efficiency are satisfactory.

Key words: sparallel computation, finite difference, aerodynamics
