Hello everyone,
I hope this email finds you well. I am currently in the process of
conducting SCF calculations utilizing the PBE0 exchange-correlation
functional. In my study, I am investigating a system composed of 44
particles exhibiting hexagonal symmetry. Due to this specific symmetry, I
have opted for the "vcut_ws" exxdiv_treatment method.
However, I have encountered an issue during the run. The calculation
terminates prematurely, accompanied by the following error message:
"non-orthorombic case untested".
I have included the entirety of my input below. I would greatly appreciate
any insights or suggestions you might have regarding the potential source
of this error. Your expertise will be invaluable in helping me identify and
rectify the issue.
Thank you in advance for your assistance.
