Hi everyone,

I am trying to apply both an electric field and excess charge 
simultaneously to my system. However, when I attempted to apply both, the 
adsorption energy I obtained was much lower than expected. Previously, when 
I applied only the electric field in my calculations, the energy was higher 
than what I obtained when there was excess charge in my system.

Specifically, I am applying a field of 0.25/A0 along the Z-direction. Could 
anyone please help me identify the error in my calculation? I have attached 
the input file for reference.

Looking forward to your reply.

Have a nice day!

Lakshmi
