Parallel Finite Element Algorithm for Three-Dimensional Inviscid and Viscous Flow

Document Type



A finite element model is developed and used to simulate three-dimensional compressible fluid flow on a massively parallel computer. The algorithm is based on a Petrov-Galerkin weighting of the convective terms in the governing equations. The discretized time-dependent equations are solved explicitly using a second-order Runge-Kutta scheme. A high degree of parallelism has been achieved utilizing a MasPar MP-2 SIMD computer. An automated conversion program is used to translate the original Fortran 77 code into the Fortran 90 needed for parallelization. This conversion program and the use of compiler directives allows the maintenance of one version of the code for use on either vector or parallel machines.
