[Gmsh] Nodes information on boundary surface.

[Xie Longtao]

Hello everyone.

How can I find all the nodes in a specific surface?

Although this information is included in the Element Section in .MSH file,

It is not easy to figure it out for me. Is there any solutions?

As boundary conditions are essential in finite element method, it is very
helpful to give
the nodes information in boundary surfaces.

By the way. I'll be appreciate if there is a section about boundary nodes
grouped by
boundary surfaces in .MSH file.


Best wishes

Xie
