I'm having some problems with Gmsh 2.5. I'm trying to mesh a pretty complicated model (250 physical volumes, 2427 physical surfaces); 2D meshing works, but 3D meshing (Delaunay algorithm) fails with this error message:<div>
<br></div><div><div>Error : Self intersecting surface mesh, computing intersections (this could take a while)</div><div>Info : 0 intersecting faces have been saved into 'intersect.pos'</div><div>Info : Done meshing 3D (330.426 s)</div>
<div>Info : 20554 vertices 59210 elements</div><div>Error : ------------------------------</div><div>Error : Mesh generation error summary</div><div>Error : 0 warnings</div><div>Error : 1 error</div><div>
Error : Check the full log for details</div><div>Error : ------------------------------</div></div><div><br></div><div><br></div><div>It seems that there are no intersecting faces, but 3D meshing still fails. Does anyone know what the issue is here? I kinda doubt it's an issue with the geometry, since sometimes Gmsh sometimes finishes.</div>
<div><br></div><div>When trying to apply Netgen (Frontal) algorithm, Gmsh just crashes. </div><div><br></div><div>Thanks,</div><div>Tibi</div><div><br></div>
