STOPCAR
Using the STOPCAR file it is possible to stop VASP during the program execution. If the STOPCAR file contains the line
LSTOP = .TRUE.
than VASP stops at the next ionic step. On the other hand, if the {{TAG|STOPCAR} file contains the line
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.
