Iterative Solutions of the 3D Transient Navier-$tokes Equations on Parallel Computers
نویسنده
چکیده
The three-dimensional, incompressible, unsteady NavierStokes equations are discretized by the spectral element method based on Legendre polynomials. High-order projection methods and a subcycling method are constructed in such a way that third-order advancement in time can be obtained. The preconditioning of the pressure operator is briefly discussed. The resulting iterative spectral element solver is implemented on the Cray T3D and on the Intel Paragon. Some issues related to parallelization are addressed. Finally, we will give some results for the numerical simulation of the three-dimensional backwardfacing-step flow on the Cray T3D.
