Thanks Oliver for the solution, and taking the time to explain how the earlier does answer my problem. Much appreciated!

Gmsh by itself does not have that functionality, but it does provide the facilities with which you could extract those things easily (post-processing the generated mesh). Just label the boundaries as 'Physical Line' (in your case, for others it might be Physical Surfaces). Then, when the mesh is generated, extract all lines that have the id you assigned to this collection of physical lines. You'll end up with a list of all the boundary nodes. Not sure what the program you're using means by "list in order", so I can't help you there. Kind regards, Oliver.

If I were to have a single list that loops around the entire shape I can manually split into the various segments without any problem. I found this http://www.geuz.org/pipermail/gmsh/2014/009188.html in the archive - but I do not think this answer my problem Thanks Melanie _______________________________________________ gmsh mailing list [email protected] http://www.geuz.org/mailman/listinfo/gmsh
