Hi all,

When I do G0W0 calculation, I find there are two parameter relative with Green's function damping, namely DmRngeXd and GDamping. Should I set them both? Is there any conflicts between them?

Dear Weiqing,

the damping of the Green function for a GW calculation is set by GDamping, while DmRngeXd is a variable that controls the variation of the damping in the calculation of the response function needed for the screening. Note the latter is considered only for a full frequency calculation. In most of the cases, you can leave them as default 0.1eV.
