[交流] 用VASP跑分子动力学,INCAR 参数中,SMASS如何选取

最近在用VASP做分子动力学,SMASS这个参数如何设置?manual上介绍比较简单,尤其是当用SMASS>=0
For SMASS>=0 a canonical ensemble is simulated using the algorithm of Nos´e. The Nos´e mass controls the frequency
of the temperature oscillations during the simulation (see [1, 2, 3]. For SMASS=0 Nos´e-mass corresponding to period
of 40 time steps will be chosen. The Nos´e-mass should be set such that the induced temperature fluctuation show approximately
the same frequencies as the typical ’phonon’-frequencies for the specific system. For liquids something
like ’phonon’-frequencies might be obtained from the spectrum of the velocity auto-correlation function. If the ionic
frequencies differ by an order of magnitude from the frequencies of the induced temperature fluctuations, Nos´e thermostat
and ionic movement might decouple leading to a non canonical ensemble. The frequency of the approximate
temperature fluctuations induced by the Nos´e-thermostat is written to the OUTCAR file.

有经验的来交流下呗,我感觉我的计算能量一直不收敛,一直上升
