Triangulation algorithm for fast elliptic solvers based on domain imbedding.

Börgers, Christoph.


  • The following triangulation problem is considered. Let R be a rectangle, and Ω an open domain whose closure is contained in R. Consider a rectangular grid covering R. Perturb this grid by shifting points close to the boundary ∂Ω onto ∂Ω. This results in a quadrilateral, almost rectangular grid. Divide each cell of this grid into two triangles along one of its diagonals. This results in a triangulation ... read more
