I didn’t use medit mesh, but did you use physical entities or default elementary entities in your geometry description? By default, when generating mesh from simple geometry with elementary entities you get all your points from the model as their own point-type elements. Use physical surface (or whatever physical). Only participating nodes will go into mesh file in this case.

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).
