Geometry Optimization with LDA+U?
Posted: Wed Apr 02, 2008 1:25 pm
Hi all,
I wonder wheter we can do a geomerry optimization using LDA+U. Are the forces calculated by LDA+U correct? Are any differences with and without U? I have my doubts about relaxing in this way when using vasp. Thanks in advance!
