Automatic blocking scheme for structured meshing in 2D multiphase flow simulation

Proceedings of the 13th Annual International Meshing Roundtable, 121--132, 2004.

We present an automatic algorithm to construct blocking scheme for multiblock structured meshes in 2D multiphase flow problems. Our solution is based on the concepts of medial axis and Delaunay triangulation. We show that the quality of the blocking scheme strongly depends on the quality of Delaunay triangulation. Therefore, well-known techniques and issues like Delaunay refinement and geometric degeneracy resurge again in multiblock structured meshes.
