WebPlease note the "BRIONS problems: POTIM should be increased", which indicates that your ionic relaxation might get stuck. --> as the total energies are not converged yet, please follow that instruction and increase POTIM in your INCAR file (default=0.5) or choose a different relaxation algorithm (IBRION) 分享: 喜欢 0 赠金笔 阅读 收藏

Web7 Apr 2024 · SIGMA = 0.05 is quite a large smearing; you should check that for SIGMA -> 0, the forces converge. Also, EDIFFG = -0.01 is not tight at all, a good value would be 10^-4; however, depending on the system, you might have a corrugated PES and you can get the convergence with 10^-4 only by carefully adjusting the POTIM parameter and gradually … WebProperties; Free Notes; Installation; Tutorials.

Re: Geometry relaxation of large system. #6 by alexey.tal » Mon Jan 17, 2024 5:04 pm. The problem with this structure is essentially the same, i.e. some atoms are too close which causes huge forces in the system. Reducing POTIM should work but it will also slow down the convergence. sept espagnol
