Hi Sahil,
I think, it would be fine if your calculation is conversed. I always recommend to check the convergence.

Re: Error in Isotropic Eliashberg equation
Hi Sahil, I see the following temp( 1) = 0.20000 K Solve isotropic Eliashberg equations on imaginary-axis Total number of frequency points nsiw( 1) = 9235 Cutoff frequency wscut = 1.0001 With nsiw(1) = 9235, N = npade * nsiw(1) / 100 (will make even by adding one if it is odd) = 8312 (with default v...

Re: Error in Isotropic Eliashberg equation
Hi Sahil,
Could you please share your 'prefix.a2f' file. I will investigate the problem myself and let you know the problem and possible solution.

Re: how to set fsthick and.....
Hi Kunsa, By default, Quantum ESPRESSO prints phonon frequency in THz and cm-1 units. Look at them, and find what is the maximum (no need of exact value). For e.g. in MgB2, I get ~800 cm-1 maximum phonon frequency, which is ~0.099184 eV and choose wscut = 1 eV (which is close to 10 times max. ph fre...

Re: Error in Calculating kgmap
Hi dsc,
Could you double check your phonon is calculated and the corresponding files are saved correctly in 'dvscf_dir = './save'' directory?

Re: Error with epwread = .true., "Restart is done without reading PWSCF save file."
Hi Prachi,
This is just a message in a restart calculation from https://gitlab.com/QEF/q-e/-/blob/devel ... pw.f90#L92. If your first step is done correctly, and corresponding files are written with no issue, no do not need to worry with this message.

Re: What's wrong with inconsistent data (names)
Hi Shi,
It looks like your phonon scf.in and EPW scf.in/nscf.in are not consistent. Please check, number of atoms, types, order of the atoms, etc.
The error appeared from the following line; https://gitlab.com/QEF/q-e/-/blob/devel ... r.f90#L361

Hi Zhou,
Can you share your plots comparing the spectral functions and lambdas for different convergence tests?

Re: About the "on the fly" mode
Hi R. Lv, On the fly mode meaning we calculate anisotropic lambda (eqn. 18 of https://journals.aps.org/prb/pdf/10.1103/PhysRevB.87.024505) for every k, q, bands, and frequencies (do not save in the memory) when it is required. In your case, I recommend using "max_memlt = 8" flag in your input file, ...

Re: EPW calculations freeze without stop and errors
Hi pfliu89,
Is your .dvscf and .dyn files saved correctly? I did not see "Calculation of q = 0.00000000 0.00000000 0.0000000" in your log.ph file, are you aware of it?
