[Gmsh] topography

[riad hassani]

Dear Gmsh users,
I wonder whether there is a convenient way to mesh a volume with the  
constraint that one of its faces fits a given topopgraphy (see the  
attached figure for an example).
I tried the following (let "truc.geo"  be the .geo file) :
1) mesh the surface of the body (2D mesh). Save the result in a file  
(say truc2d.msh),
2) by an external program and according to the topography, move the  
nodes of the corresponding face,
3) launch again gmsh, merge truc.geo and truc2d.msh. Create the 3D mesh.
This procedure seems to work provided that the lines of the 2D mesh  
are not too perturbed.

Regards,
Riad
