Dear developers,
I am trying to run BSE calculation however I am getting the following error. FIles can be found in the following link.

Re: The whole BSE has zero dimension !
Dear Burak,
in your system you have 58 filled bands:
and you asking for a BSE matrix containing no empty bands so it results in zero electron-hole pairs:
You need at least one empty band to build the BSE matrix.
Best,
Daniele
in your system you have 58 filled bands:
Code: Select all
[K+QP] Filled Bands : 58
[K+QP] Empty Bands : 59 200
Code: Select all
% BSEBands
21 | 53 | # [BSK] Bands range
%
Best,
Daniele

Dear Daniele,
Thank you for your answer! I changed the pseudopotential and I forgot to change the number of filled and empty bands. I am sorry for this simple question!
Best,
Burak
