I am doing full relaxation (ISIF=3) for a metallic system with ISMEAR=1 and in the last ionic step of relaxation the pressure is less than 1 kB but after I do static final SCF run (with ISMEAR = -5, for accurate energy) the pressure value gets increased by 50 to 60 times. Is there any way to get rid of it?
Is it because of ISMEAR flag or something else?
Thanks in advance!
