Hello Francisco,

I assume your answer is more of an answer to jordi's problem than
it is to mine, right?  I have checked your example and for as far
as I can see, the point at (0.34, 0.45) is still a node in the 
resulting mesh, so it still appears in the $Nodes section.

What I need is to be able to specify a point (the location of my
pointsource) but this point should *not* appear in the $Nodes
section.  Somehow, i would like to read the coordinates of my
pointsource from the .msh file, without having to remove it from
the $Nodes section and without having to fix all the indices in
the $Elements section.

But for as far as I can see now, there is no real solution from
within gmsh, and for now I will have to remove the node and fix
the indices in my Matlab code that reads the .msh file and sets
up the data structures for my solver.

Kind regards,
