[QE-users] unrecognized dft in phonon calculations

Dear Fabrizio,


During my calculations, I found that only this combination gives acceptable description about the system. This means this conbination must be used if we expect useful outcomes. Please tell me is there any other way to continue my calculations?


Best

Hello,
up to now not all the possible combinations of single dft terms are allowed for nonscf calculations, but only the ones identified by the 'short names'. They are listed in the comment block in Modules/funct.f90. This might change in the near future.
Cheers,
Fabrizio

Dear All,


I try to calculate phonon at gamma with input_dft='sla+pw+b88x+vdw1'. The scf calculation goes smoothly, but an error appeared in the phonon calculation. Below is the error message:


% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     task #        28
     from set_dft_from_name : error #         1
     NO SHORTNAME: unrecognized dft
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

   task #        2     from set_dft_from_name : error #         1
     NO SHORTNAME: unrecognized dft
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The input files are shown below. Please give me some idea to remove this error.
