Dear Hitoshi, in a meanwhile I have managed to solve the problem. Actually, code was not stopping, the problem was in the density of the grid I have used for scf and phonon calculations together with quite hight ecutoff. So, epw was calculating all of the files, but it took hours, which I did not ex...

Dear epw experts, I am trying to calculate anisotropic superconducting gap of NbSe2 monolayer. In the eliashberg calculation I bump into the problem with calculation of spectral function. I do not use special flag for a2f, I follow the way used in hands-on tutorial from this year (https://docs.epw-c...

Dear epw experts, recently I have been trying to calculate superconducting properties of NbSe2 using epw code. It seems that there is no problem to calculate the imaginary part of gap , but the real one (in Pade approx.) always ends as NaN regardless the npade parameter (I have tried different value...

Dear epw experts, I am trying to calculate anisotropic super. gap for NbSe2 using epw code. After successful wannierization and calculation of el. spectral function program attempts to calculate imaginary ale real part of gap for set of temperatures. However, it fails to calculate the real part end ...
