<br>
You can find details in the user manual paragraph 4.5.6 Orbital
potentials p48 .<br>
<br>
You will have to get your U/J either from the literature or by
fitting to experiment. There are also ways to determine it ab
initio via linear response which I have little experience with
(see literature again). Keep in mind that in literature you will
often only find a U value which is then an effective U obtained as
U-J.<br>
