The ISMEAR value will change depending on the type of system you are interested in. SIGMA is the width of smearing. IBRION is the amount of relaxation for a system to get the their instantaneous ground state. NSW is the maximum number of ionic steps.

WebMar 19, 2024 · 采用杂化泛函计算体材料的线性光学性质. 首先调用VASP计算得到介电函数实部和虚部,然后调用VASPKIT读取介电函数进一步得到线性光学性质。. 注意VASP计算介电函数时只考虑了带间直接跃迁,因此该方法仅适用于半导体或绝缘体体系,不适用金属体系 … 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? There are a few parameters that might be tricky, for example, ISMEAR should be different for different systems, it depends on whether the system is metal or ... http://muchong.com/html/201411/8228013.html cuddle eat hugs
