AECCAR0 has NaN value

Post by dhossain » Sat May 25, 2019 12:43 am

Dear Prof.,
I am trying to calculate core charge on each atom according to your method. But when i run the calculation after relax the structure then AECCAR0 shows NaN value which produces CHGCAR_sum with NaN as well. Could you please look at the following files and help to get rid of this error. Thanks.

Yes, I have seen problems with AECCAR0 files but I don't know why it happens. This is a question for the vasp guys.

Hi Prof.,
I have solve the problem by simply increasing the ENCUT value in INCAR. But when i used the method to get spin density, the ACF.dat file shows there is no charge. Could you help me to get the spin density please. Here is my CHGCAR and CHGCAR_sum file. Thanks for your attention.

I can't; I don't know what is going wrong. This is a problem internal to the vasp code and it needs to be sorted out by the vasp developers.
