Abstract
A GFEM without extra dof is developed. Without the extra dof, the resulting linear system becomes independent-in size-of the order of local approximation, the resulting PU approximation becomes free of linear dependence, and the resulting stiffness matrix becomes good conditioned. Numerical studies show the new GFEM's excellent convergence properties and excellent stability.
