WebDepending on the choice of parameters in the INCAR file, you may notice that the symmetry of the cell has changed. For example, see the result of the second option above here. This file will need to be modified further (see part 2 below) before use in DFPT calculations. ... ISMEAR = 0 SIGMA = 0.05 PREC = Accurate ADDGRID = .TRUE. NWRITE = 1 ... 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.

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 ... WebISMEAR determines how the partial occupancies are set for each orbital. 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. WebOur core business is HMI series development.

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. ISMEAR =−3: perform a loop over smearing-parameters supplied in the INCAR file. In this case a tag SMEARINGS = ismear 1 sigma 1 ismear 2 sigma 2 ... must be present in the INCAR file, supplying different smearing parameters. IBRION has to be set to -1 and NSW to the number of supplied pairs ismear i /sigma i.
