Hi Thomas, I’m sorry but I don’t understand your problem.  It would be helpful if you could post a small example.

I am finding that I can define a compound surface and instead of a bunch of separate meshes it treats it as one mesh but the points from the original surface divisions remain.  So the problem is that the mesh is defined based on points. The one mesh is the same as the original broken up meshes. The mesh will still be smaller on the part of the compound surface that used to be a smaller surface because points are closer together. Any fix for this? Thanks for your help!

Hi Thomas, Take a look at the Compound Line/Surface/Volume entities in Gmsh.  These will probably do what you want.

Regards,
Dave

Is there a way to mesh the whole surface as one body ignoring the lines that divide parts. For example on a simple aircraft model there will be a line dividing the metal surface from the glass of the cockpit. However, when defining a mesh I want to ignore this division and treat it as one single surface. Thanks for any help you can provide.
