Parallelization of the Fluid Dynamics Equations on Unstructured Grids

Abstract

RESEARCH OBJECTIVE: To investigate the parallelization properties of different time-integration algorithms for Computational Fluid Dynamics (CFD) on unstructured grids, i.e., to compare the scalability of several commonly-used algorithms on distributed-memory parallel processors. METHODOLOGY: The author is developing a parallel Euler solver, PUE3D, on the Intel Paragon at WPAFB. This machine is a distributed-memory machine based on the Intel i860 processor. Several different implicit and one explicit algorithm have been implemented, and encouraging preliminary results have been obtained for the Symmetric Successive Over-relaxation (SSOR) algorithm. This research effort is being funded through the Office of Naval Research (ONR) Independent Laboratory In-house Research (ILIR) program, which does not cover computer charges; therefore, the availability of the DoD HPC SRC makes this research possible.
