Charge density for Si Now we do the post-processing to extract the charge density WebFor scf calculations: default is 1.D-2 if starting from a superposition of atomic orbitals; 1.D-5 if starting from a charge density. During self consistency the threshold is automatically reduced (but never below 1.D-13) when approaching convergence. For non-scf calculations: default is (conv_thr/N elec)/10. WebIn this directory we perform a non-self-consistent (NSCF) mean-field calculation to generate all of the Bloch states needed for the subsequent GW calculations. The resulting wavefunction file will then be read as “WFNq“ by the Epsilon code. Follow these steps: Run “./02-calculate_wfnq.qsub“ to calculate the wavefunctions with PARATEC. codes for click speed
