[Gmsh] Sets of nodes

[Charles Augarde]

I often use GMSH to prepare meshes for other FE programs that require 
boundary conditions to be applied node by node, e.g. prescribed 
displacments in solid mechanics.

Is there an "easy" way in GMSH to obtain lists of nodes and their 
coordinates, along a Physical Line, say? I can see how one can obtain 
lists of _elements_ associated with a physical entity such as a line or 
a surface but cannot see how it can be done for nodes (or find anything 
in the archive to help)?

Thanks in advance

Charles
