[Pw_forum] Calculating Hubbard U of zinc in ZnO

[Shujun Hu]

Dear Drs,
I tried to calculating the Hubbard U of zinc in ZnO using the "standard" pw.x file
but got such error message:
  
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     from set_hubbard_l : error #         1
     pseudopotential not yet inserted
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
     stopping ...

I found some discussion about this error in the forum. Maybe the reason is that
elements oxygen and zinc are not included in the table in source files:
set_hubbard_u.f90 and tabd.f90. So I set up the variables as: for zinc
Hubbard_l=2, occ_loc=10 and for oxygen Hubbard_l=1, occ_loc=4. Right or wrong?  
    Best wishes

                              Shujun Hu
