SMEARINGS = [integer array]
Default: SMEARINGS = not set
Description: SMEARINGS defines the smearing parameters for ISMEAR=-3 in the calculation of the partial occupancies.
ISMEAR=-3 performs a loop over smearing-parameters supplied in the INCAR file. In this case a tag
SMEARINGS = ismear1 sigma1 ismear2 sigma2 ...
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 values ismear) . The first loop is done using the tetrahedron method with Blöchl corrections.
