Metis (v4) build good partitions when the number of partitions is 2, 3, 5, 6 and 7. For 4 partitions, results are very stranges : one of the domain is not convex, as you can see on the picture (blue domain) : http://membres.lycos.fr/astral00/metis/mesh.gif I put the graph file on the page : http://membres.lycos.fr/astral00/metis/graph.txt Same result with v4 and v3, pmetis and kmetis algorithms. But no problem with version 2. I can't see what can be wrongg. If someone can help...
