Multilevel Solvers for Unstructured Surface Meshes
Parameterization of unstructured surface meshes is of fundamental importance in many applications of Digital Geometry Processing. Such parameterization approaches give rise to large and exceedingly ill-conditioned systems which are difficult or impossible to solve without the use of sophisticated multilevel preconditioning strategies. Since the underlying meshes are very fine to begin with, suc...
متن کاملDynamic Load-Balancing For PDE Solvers Using Adaptive Unstructured Meshes
Modern PDE solvers written for time-dependent problems increasingly employ adaptive unstructured meshes (see Flaherty et al. [4]) in order to both increase e ciency and control the numerical error. If a distributed memory parallel computer is to be used, there arises the signi cant problem of dividing up the domain equally amongst the processors whilst minimising the intersubdomain dependencies...

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 کاملBoundary Treatments for Multilevel Methods on Unstructured Meshes
In applying multilevel iterative methods on unstructured meshes, the grid hierarchy can allow general coarse grids whose boundaries may be nonmatching to the boundary of the fine grid. In this case, the standard coarse-to-fine grid transfer operators with linear interpolants are not accurate enough at Neumann boundaries so special care is needed to correctly handle different types of boundary c...
