Dear developers, I get this error-message when I try to run Bethe-Salpeter equation calculation with the Coulomb cutoff technique

Code: Select all

 <50s> P100-n42: [04.01.04.01] Screened interaction header I/O
P100-n42: [ERROR] STOP signal received while in[04.01.04.01] Screened interaction header I/O
P100-n42: [ERROR] Reading File ./2D_MOD_BSE//ndb.pp_fragment_1; Variable X_Q_1; NetCDF: Start+count exceeds dimension bound

I tried to change PAR_def_mode, node(N) or number of CPUs, but they are not useful

. I have added all the relevant files to the attachment

Thanks in advance for your help.

Dear Jingda,

it seems an I/O error, and I do not think it is related to the use of the truncated coulomb potential.
Not easy to understand what's going wrong. What you can try is to remove the ndb.pp* files and recalculate the screening in the same run of BSE.
To save time, you can calculated just the static screening (em1s).

Best,
Daniele

Dear Daniele,

thank you for your reply. I have deleted ndb.pp* files, and there are currently no errors reported for the my screening calculation

. Thank you very much.
