WebJul 25, 2024 · Regarding the INCAR parameters, I just use ISMEAR = 0 , SIGMA = 0.2 , ENCUT = 500 , PREC = Accurate. I'm still learning Vasp and more generally matter simulation and CMT, so I do not fully understand what many of the INCAR parameters do. Therefore, my INCAR file is quite simple.
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.
