[Wien] Emax in case.in1 within spin-orbit coupling calculations

2012-03-19 Thread hyunjung kim
Dear all, I have some question on calculation including spin-orbit coupling (SOC). In according to the manual, the second-variational procedure requires to include many more unoccupied states to be calculated. And it can be controlled by increasing the energy maximum (Emax) which eigenvalues s

Just as the total energy will decrease asymptotically (=forever) if you increase RKMax, it will decrease asymptotically if you increase Emax. How do you find the appropriate RKMax? ==> not by monitoring the total energy as such, but either energy *differences* or your observable property of in
