# Invalid INCAR fixture for vasp.smearing.ismear_sigma_mismatch
# ISMEAR = 0 (Gaussian smearing) selects a smearing method whose width is
# governed by SIGMA (https://www.vasp.at/wiki/index.php/ISMEAR and
# https://www.vasp.at/wiki/index.php/SIGMA). Omitting SIGMA leaves the
# width at the VASP default (0.2 eV), which is rarely appropriate for
# metals or semiconductors and almost always indicates a forgotten
# keyword, so this must surface vasp.smearing.ismear_sigma_mismatch at
# warning severity, underlining the ISMEAR line.
ISMEAR = 0
