[Gmsh] remove additional info for nodes and elements from .msh file

[Martin Vymazal]

Hello Marios,

 mark your surface(s) as physical. Gmsh will save only those elements that have 
some physical tag associated with them. Take a look at gmsh reference manual, 
section 6.2:

Best regards,

I have created one *mygeometry.geo* file which contains points, lines, circles (with 
additional helping nodes to define arcs), line loops, surfaces, and a recombine 
surface definitions in 2D. From command line, I can create with *gmsh -2 
mygeometry.geo *the desired mesh with quadrilateral elements. The aforementioned 
command will produce *mygeometry.msh*. Is there any option, to remove additional 
nodes (used only for geometry purposes) from *$Nodes* block, and also all the 
elements marked with labels "15" and "1" (points and 1D line elements 
correspondigly) in *$Elements* block of .msh file? I need only "pure" mesh nodes and 
pure quad elements in msh file.

Thanks in advance!
