Abstract
A new method for adaptive tessellation of three-dimensional (3-D) grid s is presented. A mixed-element decomposition method is introduced for local refinement of fully unstructured grids, consisting of tetrahedr a and octahedra. The method preserves the shape of the elements of the initial grid and therefore the element quality, Furthermore, local an isotropies of the initial grid are preserved. The developed implementa tion allows efficient adaptation and is used in a finite element progr am for simulation of thermal diffusion processes.
