A parallel solver for unsteady incompressible 3D Navier-Stokes equations

摘要

We describe some algorithms and software components that allow us to solve on parallel computers classical test cases for unsteady incompressible 3D Navier--Stokes equations. Our main focus is the design of robust and efficient parallel solvers for systems with singularly perturbed convection-reaction-diffusion and Laplace operators, which are important con- stituents of the Navier-Stokes solvers. The performance of the solvers on two parallel com- puters is examined.
