✦ Synopsis

The present paper discusses large eddy simulations of incompressible turbulent ows in complex geometries. Attention is focused on the application of the Schur complement method for the solution of the elliptic equations arising from the fractional step procedure and=or the semi-implicit discretization of the momentum equations in velocity-pressure representation. Fast direct and iterative Poisson solvers are compared and their global e ciency evaluated both in serial and parallel architecture environments for model problems of physical relevance.

## Abstract This paper presents a detailed procedure to solve incompressible high Reynolds number turbulent flows using large eddy simulations (LES) on distributed memory machines. The filtered Navier–Stokes equations are discretized using a partial‐staggered variable arrangement and solved using a
