generating mesh from simple geometry with elementary entities you get all your

<p class=MsoNormal>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).<br>
Thanks<br clear=all>
