Unfortunately, the calculation of forces is not yet implemented <br>with the fully rotational DFT+U+J scheme (lda_plus_u_kind=1).<br>This works of course for a simplified DFT+U scheme of Matteo<br>(lda_plus_u_kind=0). Probably it is not that difficult but <br>
I did not look yet ...<br>regards,<br>Alexander <br><br><div class="gmail_quote">2012/11/10 nuttachai jutong <span dir="ltr"><<a href="mailto:nuttachai.jutong@gmail.com" target="_blank">nuttachai.jutong@gmail.com</a>></span><br>

Here is my in put file for relaxation. Actually It work if I use only<br>
