Ismear sigma

WitrynaGregor Feldbauer. A good starting point, if you are unsure what smearing to use for relaxations, is usually Gaussian smearing (ismear 0) with a small sigma value (0.05, 0.1), the sigma value should be tested and in general Gaussian smearing is bit more tricky than Methfessel-Paxton (MP) (see vasp guide, and if your system shows … Witryna1、ISMEAR 和 SIGMA 这两个关键词要联合起来使用,前者用来指定smearing 的方法,后者用来指定 smearing 的展宽——σ 值。 2、ISMEAR 和 SIGMA 的默认值分别为 1 和 0.2。 3、ISMEAR 可能的取 …
