WebJan 5, 2024 · I am wondering if there is a detailed explanation about how ASE chooses the INCAR tags, since VASP already provides default values for a lot of tags, does ASE choose the default values?

Webismear就是控制这种平滑函数的。 进行任何的静态计算或态密度计算，且k点数目（从ibzkpt文件中读取）大于4时，取ismear＝－5；当由于原胞较大而k点数目较少（小于4个）时，取ismear＝0，并设置一个合适的sigma值。 WebFor insulating materials (or materials that have unknown band gaps), I recommend using Gaussian smearing (ISMEAR=0) since it is appropriate for both conductors and insulators, although there are better choices for conducting materials. For insulating materials, I recommend settings SIGMAto 0.01 eV as a reasonable initial test.
