Three-Dimensional Grid Adaptation Using a Mixed-Element Decomposition Method
A new method for adaptive refinement of unstructured grids has been developed. This method ensures preservation of the element quality and the structural anisotropies of the initial grid. The flexibility of unstructured grids in combination with the implemented error estimation provides a powerful basis for three-dimensional simulation of time dependent processes.
