[Gmsh] Defective mesh file

[Felix Salazar]

I am using Gmsh to create a mesh for a finite element solution. However, I
am getting an error, because in the generated mesh (a medit .mesh file),
there are vertices that are not assigned to any elements in the element
connectivity list. In other words, the mesh file have nodes which does not
contain any unknown in the FEM solution. The problematic node is the origin
(0,0,0), and it is repeated at least two times. There's any way to correct
this mesh without writing a script to eliminate the phantom nodes, and
modify the connectivity list (the number of all nodes will change, so it
would be necessary to modify several hundreds of thousand of elements).
Thanks
