WebEven when the SCF converges, the wave function that is found may not correspond to a local minimum; calculations can sometimes also converge onto saddle points. Since saddle points are also extrema of the energy functional, the orbital gradient vanishes and the SCF equation F C = S C E is satisfied [1].
