[Gmsh] recombine using gmsh library

[Mikhail Artemyev]

Dear all,

How can I build a recombined mesh through the library interface like 
using a command Recombine Surface{1} in a .geo file?

I tried this:

// ...
// definition of a model, points, lines, line loop
// ...
GFace *gface = model->addPlanarFace(lineloop);
gface->meshAttributes.recombine = 1;

but it seems not working.

Thank you.
Best regards,
Mikhail
