Spectral element solutions for the Navier-Stokes equations on high-performance distributed memory parallel processors

Research output: Contribution to journalConference article

Abstract

We present a parallel spectral element method for solution of the unsteady incompressible Navier-Stokes equations in general three-dimensional geometries. The approach combines high-order spatial discretizations with iterative solution techniques in a way which exploits with high efficiency currently available medium-grained distributed-memory parallel computers. Emphasis is placed on the development of algorithm constructs which allow for solution of physically relevant problems; we specifically address the problem of parallel solution in domains of general topology. Measured performance analysis on the Intel vector hypercubes and example Navier-Stokes calculations demonstrate that parallel processing can now be considered an effective fluid mechanics analysis tool.
