Hi dear experts
I work on superconducting properties of a 2D material in order to calculate the superconducting gap

i lunched the script but it's take more than 300Go on the pc is it normal to have this size or the calculation ara wrong ?

Hi there i try constently to run the superconducting gap properties but i'm stopped by this error
[codeAt line 1290 of file io_eliashberg.f90 (unit = 108)
Fortran runtime error: Cannot open file './Al.freq': Too many open files][/code]


Hope to help me as soon as possible

Hello sir
i have another problem in the calculation

Hi dear experts i run a calculations about the superconducting gap the phonons calculations are runned in 32x20x1 kmesh points and 16x10x1 q mesh points in the superconducting grid i put nkf1=320 nkf2=200 nkf3=1 nqf1=320 nqf2=200 nqf3=1 i had this message of error Error in routine epw_readin (1): ca...

Hello dear administrators and users
i have a question about the superconducting gap on the superconductors type 1
can i calculate it on using EPW

hey
you can change directy the temperature and see the effect on the electron phonon coupling or linewidth

Hi all i try to find the electron phonon coupling in aluminene but i don't found a good results like the literature this is the input -- kmaps = .false. epbwrite = .true. epbread = .false. ! etf_mem = 0 epwwrite = .true. epwread = .false. nbndsub = 8 nbndskip = 0 wannierize = .true. num_iter = 150 i...

Hi i have the same problem for aluminene

HI i have the same problem for the electron phonon coupling for an 2D metal i got unreasonable electron phonon coupling and eliashberg spectral function for a q and k meshes 320*200*1 and 320*200*1 i had lambda = 290 &inputepw prefix = 'xx' amass(1) = xxxxxxxxxx outdir = './' iverbosity = 1 !ep_...

hi all

any suggestion the solve the problem
