POMASS, ZVAL

POMASS= [real] $ \qquad$ ZVAL= [real]

Default    
POMASS = values read from POTCAR
ZVAL = values read from POTCAR



$\displaystyle \vspace*{1mm} {\tt POMASS}$ $\displaystyle =$ mass each atomic species, in a.u.  
$\displaystyle {\tt ZVAL}$ $\displaystyle =$ valence for each atomic species  


These two lines determine the valency and the atomic mass of each atomic species, and should be omitted usually since the values are read from the POTCAR file. If incompatibilities exist, VASP will stop.
