[Gmsh] Exporting only physical mesh

[Ganesh Diwan]

Dear GMsh

I create a 2D mesh from a surface with a B-spline as its bounding line.
However, when its mesh is exported, all the points originally used to
create the B-spline also get exported as nodes of the mesh. Is there a way
to export only the true mesh i.e. nodes and elements that belong to the
physical surface alone and not B-spline.

Thanks in advance for help
Ganesh
