NSW only gives the number of steps, irrespective of whether any kind of convergence is reached. To check for energy convergence, (in a MD run) set EDIFFG to a positive value, depending on the maximum E fluctuations you want to allow for

I am still a little confused here.Since, as said in VASP manual(p55)"EDIFFG does not apply for MD-simulations",what does it mean?
