Job Restarts : ICHARG = 0 | 1

[Sinner]

Hi.

I got a quite simple question (well I guess it's quite simple) about the value I should set to ICHARG when trying to restart a job.

I used to set ICHARG = 1 for restarting a job, but I read on the VASP guide that it wasn't the best way to do, and I was adviced to set ICHARG to 0, so that VASP would read the charge density in the WAVECAR file rather than the CHGCAR file.

Should I then set my ICHARG value to 1 when restarting a job ?

Thanks in advance,

Regards.

Z.
