[Gmsh] writing support points in mesh file

[nijso beishuizen]

Dear all,

If you create a circle, you need a support point, the middle of the
circle. If I write a mesh file (e.g. in SU2 format), the support point
is included in the list of points. This then gives problems with SU2
because there are more actual nodes than used nodes.

So: I would like to delete all points that are not used in the actual
mesh. 

Is there a way to force gmsh to skip the writing of points that are not
used in the mesh?


Best regards,
