Hello everyone,
I hope this message finds you well. I am currently facing a challenge in a
'relax' type calculation, specifically when introducing a Br anion into my
system with a total charge of -1. The issue arises as the calculation stops
after just 2 SCF iterations, accompanied by the following error message:
Error in routine rdiaghg (640):
problems computing cholesky
Interestingly, the calculation was running smoothly before the introduction
of Br into the system. For context, I am utilizing the PBEsol paw type pp
from the pseudo dojo database, and the input file is written below for your
reference.
