Diego Ontiveros

Make sure the LCHARG and LWAVE tags are set equal to .TRUE. in the INCAR. You can also try to do a single point calculation with the optimized CONTCAR to just get the CHGCAR and WAVECAR. Has the CHG file been written?

Jennifer Cuellar

Hi, Diego thank you very much for your answer, yes it is generating the CHG but as in the other files it generates it empty, I will check the INCAR and I will apply what you suggested.
