Hi,
If it is not the case, you should try with a recent version of Gmsh. In the release notes ( http://www.geuz.org/gmsh/doc/VERSIONS.txt ) of the 2.9.0 version you can find: "improved reproductibility of 2D and 3D meshes;", and for the 2.8.4 version: "better reproductibility of 2D meshes;"

Hello, Thank you for this great mesh tool ! I obtain (slightly) different results when running GMSH from the same geometry (.geo file) : - on different (linux CentOS 6.7) stations - on the same machine but from different users For example two different users have obtained the following different results on the same station : First user : 86048 vertices 553346 elements 382088 tetrahedra Statistics: Input points: 50580 Input facets: 101156 Input segments: 151734 Input holes: 0 Input regions: 0 Mesh points: 50580 Mesh tetrahedra: 151938 Mesh faces: 354454 Mesh edges: 253095 Mesh faces on exterior boundary: 101156 Mesh edges on exterior boundary: 151734 Mesh faces on input facets: 101156 Mesh edges on input segments: 151734 Info : 50580 points 253095 edges and 101156 faces in the initial mesh Info : Found region 1 Info : 0 points created - Worst tet radius is 24.375 (PTS removed 0 0) Info : 4927 points created - Worst tet radius is 1.73689 (PTS removed 0 73) Info : 9901 points created - Worst tet radius is 1.45257 (PTS removed 0 99) Info : 14867 points created - Worst tet radius is 1.29636 (PTS removed 0 133) Info : 19826 points created - Worst tet radius is 1.1871 (PTS removed 0 174) Info : 24786 points created - Worst tet radius is 1.10673 (PTS removed 0 214) Info : 29730 points created - Worst tet radius is 1.05069 (PTS removed 0 270) Info : 34664 points created - Worst tet radius is 1.00635 (PTS removed 0 336) Info : 3D point insertion terminated (86048 points created): Info : - 344 Delaunay cavities modified for star shapeness Info : - 340 points could not be inserted Info : - 382088 tetrahedra created in 6.25905 sec.
