A Fast Solver for Incompressible Navier-stokes Equations with Finite Difference Methods
نویسنده
چکیده
In this paper, a fast direct solver for incompressible Navier-Stokes equations with nite diierence methods on the half-staggered grid is presented. To achieve this, new algorithms for diagonalizing a semi-deenite pair are developed. Our fast solver can also be extended to three dimensional case. The motivation and related issues in using this second kind of staggered grid are also discussed.

A Fast Poisson Solver for the Finite Difference Solution of the Incompressible Navier-Stokes Equations
In this paper, a fast direct solver for the Poisson equation on the half-staggered grid is presented. The Poisson equation results from the projection method of the finite difference solution of the incompressible Navier–Stokes equations. To achieve our goal, new algorithms for diagonalizing a semidefinite pair are developed. The fast solver can also be extended to the three-dimensional case. T...
متن کاملA Fast Finite Difference Method for Solving Navier-stokes Equations on Irregular Domains
A fast finite difference method is proposed to solve the incompressible Navier-Stokes equations defined on a general domain. The method is based on the vorticity stream-function formulation and a fast Poisson solver defined on a general domain using the immersed interface method. The key to the new method is the fast Poisson solver for general domains and the interpolation scheme for the bounda...

متن کاملA Parallel Multigrid Solver for Time-Periodic Incompressible Navier-Stokes Equations in 3D
In this talk, we consider the efficient solution of the discrete and nonlinear systems arising from the discretization of the Navier-Stokes equations with Finite Differences. In particular we study the incompressible, unsteady Navier-Stokes equations with periodic boundary condition in time. Our approach is based on a space-time multigrid method, which allows for parallelization in space as wel...
