<br><font size=3>Actually, that solution does solve your problem. 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). </font>
<p><font size=3>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. </font>
<p><font size=3>Not sure what the program you're using means by "list
in order", so I can't help you there.</font>

<br><font size=3 face="sans-serif">Hi,</font><font size=3> <br>
</font><font size=3 face="sans-serif"><br>
In order to use my gMSh generated mesh in another program I need to list,
in order, the nodes that make up the various boundaries of the domain -
is there a way to do this in gMSh?</font><font size=3> <br>
</font><font size=3 face="sans-serif"><br>
as an example, I have the mesh</font><font size=3> <br>
</font><img src=cid:_1_0CAE34200CAE2E1800826750CA257D5A width=763 height=680 style="border:0px solid;"><font size=3 face="sans-serif"><br>
and want to be able to extract that one boundary segment is 1 - 8 - 2 -3,
a second is 3-4-5, a third 5 - 6 - 7 and the final 7 - 9 - 1. 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.</font><font size=3>
