Application of the computer simulation for solving the incompressible flow problems motivates developing efficient and accurate numerical models. The set of Inviscid Incompressible Euler equations can be applied for wide range of engineering applications. For the steady state problems, the equation of continuity can be simultaneously solved with the equations of motion in a coupled manner using...

Multigrid is a popular solution method for the set of linear algebraic equations that arise from PDEs discretized with the nite element method. The application of multigrid to unstructured grid problems, however, is not well developed. We discuss a method that uses many of the same techniques as the nite element method itself, to apply standard multigrid algorithms to unstructured nite element ...

The growing class of applicationswhich solve partial differential equations (PDEs) on unstructured adaptive meshes is considered. Solution to such sparse, non-symmetric and in most cases ill-conditioned systems is often obtained using iterative methods. This paper describes the specification and implementationof the Parallel Library for Unstructured Mesh Problems (PLUMP), which supports the tra...
