I calculated for Sn (mp-117) using VASP 6.2.0 version.
However, my calculations(3.83eV/atom) and MP data (-4.01eV/atom) were different.
(MP is materialsproject)
I want to use Sn energy of my calculation as a reference element,
but I doubt whether it can be used due to the large difference (0.18 eV/atom) in energy value with MP data.
Please advice from seniors.
My calculation environment is as follows.
POSCAR = MP
INCAR = MP (Only ISMEAR changed from -5 to 1.)
KPOINTS = MP
POTCAR = Sn_d(POT_GGA_PAW_PBE_54)
