[求助] castep中能量计算输出文件*。castep中几个能量的区别

Therefore, CASTEP uses the Mermin finite temperature expression for the total energy (Marzari, 1997): E = EKS - TS, where T is the temperature (i.e., smearing width) and S is the Mermin entropy due to the different ways in which the partially filled bands could have been filled.

The CASTEP output is as follows. The line

Final energy, E             =  -861.8315373731     eV

gives the Kohn-Sham energy, EKS, which ignores the entropy. However, it is the total Mermin free energy that is minimized by CASTEP and reported in the SCF cycles in the line

Final free energy (E-TS)    =  -861.8315374521     eV

If you were actually interested in the electronic states at some reasonable nonzero temperature, you would smear the Fermi level with a thermal (i.e., Fermi-Dirac) smearing method and the free energy reported by CASTEP would be the value you require.
中Final energy, E和Final free energy (E-TS),以及Pseudo atomic calculation performed for Fe 3d6 4s2    Converged in 37 iterations to a total energy of -855.8641 eV的区别

自己给答案吧,通常我们选择使用的时Final free energy (E-TS)    =  -861.8315374521     eV,即把这个当做我们计算体系的最终总能量。Pseudo atomic calculation performed for Fe 3d6 4s2    Converged in 37 iterations to a total energy of -855.8641 eV可以认为是在计算时MS选用的原子的能量。
