WebThe SCF calculation involves inner and outer loops. If the inner SCF loop does not converge in the desired number of steps (set in MAX_SCF) then the inner loop will exit in order to prevent wasting time heading in the wrong direction. The preconditioner is recalculated and then a new inner loop SCF begins, with the number of outer steps ...
