Abstract

A mixed spectral element, pseudospectral, and finite-difference scheme for solving the Navier-Stokes equations is implemented on a Meiko parallel supercomputer. The code for the solution of Navier-Stokes equations for jetlike flows is implemented with a spectral scheme in cross-flow directions, a spectral element scheme in the stream-wise direction, and finite-difference marching in time. Several strategies for distributing the workload onto the processors are discussed. Special attention is paid to using the flexible topology of the Meiko.
