EPW Forum

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 encounter the same question too?Can someone give some advices or comments?

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."
