Abstract : A blockstructured solution scheme was developed for the solution of threedimensional Euler equations around complex geometric configurations. The overall effort included the development of a blockstructured solution of both potential and Euler equations. The flow field around a complex geometry is divided into blocks with simple geometries. The computational grid is generated individually for each of the blocks and coupled automatically. For each of the blocks, either potential of Euler equations are solved independently using the finite element method. The normal mass and entropy fluxes are balanced between the blocks iteratively by using a relaxation scheme. This scheme is implemented on large computers (Cray and IBM) using parallel precessing capabilities such as asynchronous I/O and several CPU's.
