[Wien] A confirmation is needed about mbj+so

2017-07-11 Thread fatima DFT
Hello, I just finished some calculation with PBE/PBE+SO/mBJ+SO. I know that with mBJ we can not do force optimization. I know how to do force optimization with -SO I have done PBE+mBJ calculation save_lapw -d case initso_lapw and fixed position for some atoms and then started min -j "run_lapw -ec

You are doing a structure optimization via MSR1a (-min) Why should the optimization stop when -cc is fulfilled ? It will continue until the forces are small enough and the atoms are not moved much anymore. :FRMSA shows that your 2 mRy criterium is not fulfilled 3 times in a row, because atoms

Several things immediately: a) What is the :WARNING due to? Do "grep -e :WARN *scf", you should never ignore them. b) It is making relatively large changes in the atom position -- worth seeing what they are. c) The GREED is small, it should not normally be. On Tue, Jul 11, 2017 at 2:31 PM, Luis O

Dear Prof. Marks, Thank you very much for your explanation. Unfortunatelly, I am stil using Wien2k 14.2, without the "Check" command. Anyway, I can wait for the charge convergence (for a while). If it takes too long and nothing bad happens, I will "kill" the optimization. Thank you aga

In case no one has answered this up to now: ad 1) The procedure itself is ok. You might want switch on SO first and converge that without the orbital potential to establish a zero-field base line. Remember to put in LARGE fields - your off-the-shelf lab field of 10 T will not show up at any en

It is possible for :ENE (Energy, -ec) to seem to converge, but has not -- so it is always wise IMO to also use the charge converge (:DIS, -cc). A value of .0004130 is probably OK, I suggest using the "Check" command which gives more information. (Peter added it to version 16, presumably 17 as well

Dear Prof. Marks and Wien2k community, Good afternoon ! Just a curiosity about the charge convergence criteria. I am optimizing a supercell and the charge convergence limit I am using is 0.001. The same numerical value for the energy convergence. The energy is finally converged, but the c

Another "misuse" of U might be to shift the binding energies of the Lu 4f electrons in "nonmagnetic" compounds without U the Lu 4f doublet appears, roughly speeking, centered at about -5eV, with a moderate U of 0.5 Ry one can shift it to the value found in photoelectron spectroscopy at about -9e
