Dear feng_lei2000:

Could you let me know which version of EPW you are using and provide your EPW input and output files?

Sincerely,

H. Lee

Now，the problem has been resolved. But new erro comes.

The erro in epw1.out

Dear feng_lei2000:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Error in routine set_u_matrix (1):
xaxis and zaxis are not orthogonal!
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Your error is not directly related to EPW; you encountered the error in the preparation step for Wannierization.
Please provide (1) full outputs of EPW (epw1.out) and Wannier90 (W90) (BeAlB.wout), and (2) *.win (EPW generates this file) and nscf.in .

Sincerely,

H. Lee

Dear feng_lei2000:

Your error originates from the fact that you calculated 4 bands from nscf calculations, but you specified 5 projections for Wannierization.

From nscf.in
nbnd = 4
From epw1.in
proj(1) = 'Be:l=0'
proj(2) = 'Al:l=1'
proj(3) = 'B:l=0'
If you need to specify 5 projections, you have to remove the statement of "nbnd = 4" in nscf.in or increase the value of nbnd.
Also you have to know which one between the isolated band manifold and the entangled band manifold is suitable to your problem.
Please check the Wannier90 documents.

Sincerely,

H. Lee

Dear feng_lei2000:
Program EPW v.5.2.0 starts on 3Jan2005 at 4:51:21
Since you are using EPW v5.2, you should add the list of q points to the end of epw1.in ; please check the section of "Structure of the input data" at https://docs.epw-code.org/doc/Inputs52. ... input-data :

If you don't want to add the q-point list, you should use EPW v5.3 included in QE v6.6 or v5.3.1 included in QE v6.7; you can download the latter at https://gitlab.com/QEF/q-e/-/releases .

I would suggest you to use the recent version of EPW since it fixes several bugs or issues.

Sincerely,

H. Lee

dear H. Lee
I am very grateful for your rapid reply. I use QE6.7 to calculate but I also get into trouble after a long running. And there is no erro report in epw1.out and BeAlB.wout files.

Dear feng_lei2000:

Your error seems to be related to unphysical results of your calculation and I would suggest you to tune some parameters in your epw1.in .

Your calculation was not converged up to 1000 iterations and the following two lines indicate that something wrong happens in your calculation.

(from epw1.out)
Estimated Allen-Dynes Tc = ************ K for muc = 0.16000
(from epw1.out)

Please check the tutorials, etc before performing the production run.
