Tetrahedral mesh generation for a domain with three materials. (a) - a wireframe visualization; (b) -the constructed triangular surface mesh; (c) - one cross-section of the constructed tetrahedral mesh; (d) - the surface mesh is improved by using edge-contraction and geometric flow (100 steps with step length 0.01).
