<DIV><FONT size=3>Dear wien2k master:</FONT></DIV>
<DIV><FONT size=3> Can wien2k give the external pressure of the unit cell ? I know min_lapw can optimize the internal force between atoms in the unit cell, and we can get the internal forces by :FGL***. But I am more intersted the external pressure(stress) of the whole unit cell when opimizing the volumn of unit cell ? </FONT></DIV>
<DIV><FONT size=3> By the way, I checked the userguide, and I found in case.in2, there is a parameter 'FOR' which can calculate the Pulay force. Is this Pulay force the exteranl pressure I am looking for ? ( if it is , userguide said only need to calculate at the final scf, is this right enough ?)</FONT></DIV>
<DIV><FONT size=3> Thanks:)</FONT></DIV>
