[QE-users] Relax approaches

[pmoreira at ifi.unicamp.br]

  Dear all users,

  I am trying to relax a system, but it has been very trick. So, I  
have followed the approaches described at:

https://www.quantum-espresso.org/Doc/cp_user_guide/node9.html

  I note some commands are not in input file description at:

https://www.quantum-espresso.org/Doc/INPUT_PW.html#__top__

  For example:

       ion_damping = 0.2,
       ion_dynamics = 'none'


   Which is website page out-dated?

   About my issue. My system has little atoms with forces components  
around 0.005 a.u when I relaxed using "damp" or "bfgs" dynamics. I  
would like no atom has forces greater than 0.002. Does anyone have a  
suggestion for get lower forces?

  With best regards,
