[QE-users] Unrecognized dft when specifying BEEF-vdW functional

[Jibiao Li]

Hi, All
Isn't the BEEF functional included in LIBXC 4.3.4? Does the errors suggest that it may not be included in LIBXC 4.3.4? 
Best

Hello,
I don't know much about BEEF functionals, but the corresponding library in QE (LIBBEEF, which is independent from libxc) was added quite recently. Perhaps you should try with the develop version of QE.
Hope it helps, cheers

Dear QE experts,


I am performing calculations using QE6.4.1 with LIBXC 4.3.4. However, no matter how I specify input_dft in the input file, the following error message appears:



 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     task #         2
     from set_dft_from_name : error #         1
     BEEF: unrecognized dft
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%



 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     task #        12
     from set_dft_from_name : error #         1
     BEEFVDW: unrecognized dft
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     task #        41
     from set_dft_from_name : error #         1
     BEEF_VDW: unrecognized dft
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     task #        18
     from set_dft_from_name : error #         1
     BEEF-VDW: unrecognized dft
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%



Does any one know how should I specify input_dft when using BEEF-vdW functional?


Thank you so much! I need your help
