Abstract
An effective, efficiently parallelized Poisson solver suitable for complex geometries has been developed and assessed for three-dimensional problems in both Cartesian and cylindrical coordinate systems with at least one homogeneous direction. It uses spectral and/or high-order finite difference collocation discretizations along with direct sub-structuring. and possesses spectral accuracy. The accuracy and performance behavior of the solver are investigated varying domain complexity, grid size and number of processors for different test functions and boundary conditions. The objective is to incorporate it in a 3-D code with a splitting time-scheme for turbulent incompressible flow simulations. © 2000 The American Institute of Aeronautics and Astronautics, Inc.
