BSEPREC = Low | Medium | High | Accurate
Default: BSEPREC = Medium 


Description: BSEPREC determines the precision for the time-evolution calculation in BSE and TDDFT, i.e., the step size and the number of steps.

The timestep size in the time-evolution calculation is inversely proportional to the maximum transition energy OMEGAMAX and the number of steps is inversely proportional to the broadening CSHIFT. BSEPREC defines

BSEPREC OMEGAMAX CSHIFT
Accurate (a) ×4 ×10
High (h) ×3 ×7.5
Medium (m) ×2.5 ×6.25
Low (l) ×2 ×5
