Mahasin: You are very close. Trying using calculation='vc-relax'. Don't forget to add an &CELL section to your input.
Here is the relevant section of the manual: http://www.quantum-espresso.org/input-syntax/INPUT_PW.html#id3667252 Mike michael at ihpc.a-star.edu.sg http://www.sullivan.sg/ From: pw_forum-bounces at pwscf.org [mailto:[email protected]] On Behalf Of MAHASIN ALAM Sent: Thursday, August 06, 2009 4:54 PM To: pwscf Subject: [Pw_forum] Geometry Optimization Dear Friends, For geometry opimization in PWSCF (QE) it mentioned in the manual that we have to set calculation = 'relax'. If I set it, it will only relax the ions. But if I have a system with vacuum cell and if I need to relax the ions as well as vacuum cell, can I do it using PWSCF? If yes can any one tell me what I have to set in calculation type? Thank you for your help. Regards Mahasin ________________________________ This email is confidential and may be privileged.
