Multigrid approaches to non-linear diffusion problems on unstructured meshes
The e ciency of three multigrid methods for solving highly non-linear di usion problems on two-dimensional unstructured meshes is examined. The three multigrid methods di er mainly in the manner in which the non-linearities of the governing equations are handled. These comprise a non-linear full approximation storage (FAS) multigrid method which is used to solve the non-linear equations directl...
متن کاملMultigrid Techniques for Unstructured Meshes
An overview of current multigrid techniques for unstructured meshes is given. The basic principles of the multigrid approach are first outlined. Application of these principles to unstructured mesh problems is then described, illustrating various different approaches, and giving examples of practical applications. Advanced multigrid topics, such as the use of algebraic multigrid methods, and th...
متن کاملMultigrid Acceleration of an Upwind Euler Solver on Unstructured Meshes
Multigrid acceleration has been implemented for an upwind ow solver on unstructured meshes. The ow solver is a straightforward implementation of Barth and Jespersen's unstructured scheme, with least-squares linear reconstruction and a directional implementation of Venkatakr-ishnan's limiter. The multigrid scheme itself is designed to work on mesh systems which are not nested, allowing great exi...
متن کاملMultigrid Strategies for Viscous Flow Solvers on Anisotropic Unstructured Meshes
Unstructured multigrid techniques for relieving the stiffness associated with high-Reynolds number viscous flow simulations on extremely stretched grids are investigated. One approach consists of employing a semi-coarsening or directional-coarsening technique, based on the directions of strong coupling within the mesh, in order to construct more optimal coarse grid levels. An alternate approach...
متن کاملDomain Decomposition and Multigrid Algorithms for Elliptic Problems on Unstructured Meshes
Multigrid and domain decomposition methods have proven to be versatile methods for the iterative solution of linear and nonlinear systems of equations arising from the discretization of partial differential equations. The efficiency of these methods derives from the use of a grid hierarchy. In some applications to problems on unstructured grids, however, no natural multilevel structure of the g...
