Dear developer,
I faced exactly the problem mentioned above for slepc solver. When I used "ypp -e s 1 -J ...." for bulk hBN,exciton energies were extracted correctly. But when I used ypp for my material, I received following error:
Code: Select all
[ERROR] STOP signal received while in[06] Excitonic Properties @ Q-index #1
[ERROR] ndb.BS_diago not found
Is there a way to solve this problem and extract the excitonic wavefunvtions from the ndb.BS-diago-Q database?
Given that this problem may be solvable using Yambo-4.5, is there a way to convert the ndb.BS-diago-Q database obtained from Yambo-5.0 to Yambo-4.5 without recalculation?
The report files for bulk hBN and my material are attached.
Thanks and Regards,
Mitra Helmi
