I want to run molecular dynamics (MD) simulations with VASP for Mg2Si to investigate the simulation time vs
KPOINTS, but I do not know how to set INCAR tags for example for the first run if
ENCUT = 500 eV with 100fs time then should I change the value of
ENCUT and time for the second run? What parameters of
INCAR will remain the same to compare
ENCUT with simulation time and to get one plot of energy convergence? If the first run goes well should I change my
POSCAR too for the second run as input?
