about the error when calculating lifetime

Concerns issues with computing quasiparticle corrections to the DFT eigenvalues - i.e., the self-energy within the GW approximation (-g n), or considering the Hartree-Fock exchange only (-x)

about the error when calculating lifetime

Post by kjzhang » Sat Sep 20, 2014 10:32 am

Hi everyone,
I use QE/Yambo to calculte the lifetime of Al(fcc).First I used QE to calculte KS states of Al(the k-points 10*10*10 and 20 bands),
then run yambo to calculte lifetime,everything is fine. BUT when I increase k-points(12*12*12) in the inputfile of QE,after running
yambo,error occures like this:
[ERROR] STOP signal received while in :[04.03] Dynamical Dielectric Matrix
[ERROR]Incomplete Parallel Index Filling

I don't know how to figure it out.
Thanks!
