Parallel Computation of Unsteady Flows on Network of Workstations

A parallel algorithm is presented for explicit solution of compressible Euler equations. Upwinded forms of the equations are used in conjunction with the finite element formulation. The solution domain is subdivided into overlapped blocks which are distributed to available workstations. Parallelization is achieved by using a machine portable parallel library. This, together with the usage of an explicit time-integration scheme, makes the implementation of the algorithm on distributed systems a rather straight-forward task. Furthermore, it provides a very flexible platform for load balancing of available computers.
