Web另一方面，ediffg所设的力收敛值仅对非固定原子有效，而固定原子受力不受此阈值限制。因此，存在固定原子时，即使力已收敛，outcar中原子最大受力也可能大于我们所设的力收敛标准。检查力的收敛，需要排除掉固定原子的受力值。 WebDec 9, 2024 · 前面我们一直在说ediff和ediffg对计算时间的影响。为了给大家一个感性的认识，现在我们用O$_2$分子的计算作为测试例子，将结果展示出来。这两个参数主要是在计算精度上影响计算时间，很容易想到，精度越高，收敛的越慢，需要的时间对应的也会更长。 WebStarting January 30, 2024 City Hall will be open from 7:30 a.m. to 12:00 p.m. and 12:30 p.m. to 4:00 p.m. Subscribe here to view both live and recorded city council meetings!

Sometines, when the energy is converged the force is still 0.09 eV/ang or more. And EDIFFG=-0.01 is accepted considering force as convergence.

1）EDIFF：控制电子步收敛（前后能量差值），默认EDIFF=1E-4，建议1E-5即可。 2） EDIFFG：控制离子步收敛。默认采用能量收敛，EDIFFG=EDIFF×10. 1. （1）力作为收敛标准，此时EDIFFG为负值。一般取-0.01到-0.05之间； 2. （2）能量作为收敛标准，此时EDIFFG为正值。一般取0.0001到0.001即可。三、VASP中控 … See more WebJan 4, 2024 · （9）改变收敛标准：几何优化的一般ediffg= -0.02，过渡态ediffg=-0.03. 对于体系较大难以收敛的体系，见到文献里有用EDIFFG= -0.05的。但是不建议使用更大的收敛标准了。
