Dear wien2k's users as Rocquefelet said "
To conclude, when I use LDA+U or GGA+U, I always consider a set of properties. I choose the Ueff value to reproduce one property and then I use this Ueff value to predict the others. For sure it can be problematic in some cases but it works quite nicely in general." Can we use theses methodes to calculate the room temperature properties of a material if we reproduce the room temperature lattice constants with the parameter U best wishes -- Mr: A.Reggad Laboratoire de Génie Physique Université Ibn Khaldoun - Tiaret Algerie
