Hi

maybe the problem is related with ROKS? Try to run with LSD
to see if the problem persists.

Dear Vladimir,

Thanks for your quick reply. I changed to integer (-1). But the problem persists. From the output, CP2K did realize the charge set. Btw, I am using version 5.1.

Followings are part of the output:

Dear Xiaoming,

the charge should be integer (-1) rather than real (-1.0). Newer versions of CP2K will actually generate an error. I believe your version ignores the improper input and uses the default, which is 0.

Yours,

Vladimir

Hello,

I am doing a charged calculation on solid Ne with CHARGE -1.0. However, in the output the total charge from Hirshfield analysis is 0. And the total energy is the same as that of neutral system. What's going wrong?
