Potim should be increased

Web初学vasp,手册里说ibrion为2时,potim的默认值为0.5。不过看教程里说,当potim过大时有可能会错过真正的能量极小点(教程中是一个分子,比较容易判断这个优化结构是否准确)。但是当体系复杂时,直观判断就变得困难了。 http://bbs.keinsci.com/thread-17175-1-1.html

Web12 Jun 2006 · Initially, I use the NEB method without Climbing Image and I use IBRION=3 and POTIM=0.01 for several steps (e.g. 5). Then I copy CONTCAR to POSCAR, and use IBRION=1, POTIM=0.1 to converge the maxmum force in every degree of freedom to within 0.01 eV/A. Finally, the CI-NEB method is activated and IBRION=1, POTIM =0.1 are still used. Web您的密码: 右边的数字验证码: 注册帐号: 找回密码: 确认登录: Copyright © 2011 - 2024 cailiaoren.com. All rights reserved.
