Tetrahedral Grid Optimisation: Towards a Structured Tetrahedral Grid.

摘要

In the paper algorithms for optimising a tetrahedral grid are proposed. In order to obtain an optimised tetrahedral grid a new concept is introduced, namely: a structured tetrahedral grid. This grid type fits naturally into the classification of grid types. The tetrahedral optimization algorithm consists of two components: An algorithm to optimise the grid connectivity and an equi-distribution algorithm to optimise the cell size of the tetrahedral elements.
