I used to mesh the attached geometry file easily with Gmsh 2.5 UI or Gmsh r15203 non-interactive, resulting in a very nice and smooth graded mesh. However, in the later revisions (r15256 non-interactive or r15299 with the UI), the characteristic lengths of the internal points is ignored. I've attached 2 screenshots with the resultant meshes for your view.<br>I have tried varying the characteristic lengths, but it seems that only those of the boundary or external points are used. Do you know what may be going wrong in my geometry file? Do I have to change something, for instance a meshing option, to force the mesh to use the specified mesh lengths? Or can this be an issue with the updates in Gmsh?<br><br>Thank you,<br>Omid<br><br>-- <br>Omid Mahabadi<br>Geomechanica, Inc.<br>Tel: (647) 478-9767 x824<br><br><span><open_pit_base_geom_no_internal_lines.geo></span><span><new_gmsh.png></span><span><old_gmsh.png></span>_______________________________________________<br>gmsh mailing list<br><a href="mailto:gmsh@geuz.org">gmsh@geuz.org</a><br>http://www.geuz.org/mailman/listinfo/gmsh<br></blockquote></div><br><div apple-content-edited="true">
