[Gmsh] Structured mesh from Refine by Splitting.

[Fabio Naddei]

Hi all,

I need to perform some operations on a grid using an external tool. For 
this purpose I am generating a block structured grid with the proper use 
of geometrical progression, then I need to refine this grid by 
splitting. I really need the new grid points to be in the middle of the 
previous ones. Then I need to save this grid in the p3d format. When I 
export this grid in p3d it completely loses the refinement that I had 
already performed. My guess is that the refined information is not added 
to the structured information. Is there any way to do this?

An alternative for me would be to be able to generate manually the 
progression of points  for the transfinite lines. This would allow me to 
apply the proper progression and generate the mid points.

Thanks

Fabio Naddei
