STOPCAR
During the VASP program execution, we can creat a file names STOPCAR to stop the program. If the STOPCAR contains the line:
1
LSTOP = .TRUE.
then VASP will stop at the next ionic step.
If the STOPCAR contains the line:
1
LABORT = .TRUE.
VASP stops at the next electronic step, i.e. WAVECAR and CHGCAR might contain non converged results.
If possible use the first option.
