[Gmsh] Postprocessing view with triangles indices instead of coordinates ?

[gilles quemener]

Hello, 

Currently I am using, in an external program, some GMSH/GETDP postprocessing views of a 
scalar field calculated on linear elements. The .pos file contains lines like the following: 

ST(0,0.9,0,0.2666666666660086,0.9,0,0,1.3,0){3.194654609503308,3.099105137740456,3.009640920970774}; 

with the x,y,z coordinates of the 3 triangle corners between the parenthesis and the associated scalar potential 
between the brackets. Is there a function or a method to obtain something like: 

ST(corner1ID, corner2ID, corner3ID){scalar_at_corner1, scalar_at_corner2, scalar_at_corner3}; 

where corner1ID, etc ... are the points indices contained in the mesh file of the problem ? 

Thanks for any help, 

Gilles
