Error in Fermi Energy - Ef cannot bracket

Post by jir520 »

Dear EPW users

I got the error " Ef cannot bracket" in my epw.out file for Aluminum. I was using nbndsub= 4 ,nbndskip= 0, proj(1) = 'f=0,0,0:l=-3' with default values for dis_win_max and dis_froz_max. However the epw2 and epw3 finished without errors.

I tried to solve this by some guessed values for dis_win_max and dis_froz_max. Also tried by random projections. But still it is the same.

I appreciate if some one can help me for this.

Thank you

I set the efermi_read and fermi_energy in the epw.in file; the error disappear! I cannot tell why. Anyone can tell me is it appropriate to do this? :?:

Dear Ruichun

It is appropriate to do that as long as the wannierized band structure appears ok, it is advisable to always check that using "band_plot=.true."
