Parallelisation of a Navier-Stokes Code on a Cluster of Workstations

An existing Navier-Stokes code (Aeroshape-3D) was parallelised on a cluster of workstations having Message Passing Interface implementation. The parallelisation was done by domain decomposition and incorporating features like parallel communication and load balancing. The parallelisation efficiency achieved for a practical three dimensional problem on a cluster of 8 Dec-Alpha workstations was above 90%. With this capability it is now possible to compute flow field over complex bodies in a reasonable time frame.
