[Pw_forum] phonon dispersion by using optimized tetrahedron method

[Enamul Haque]

Dear Dr. Mitsuaki Kawamura,

Thank you for your great information. Can you please tell me, how to do so?
Basically, after calculation of dynamical matrix, then can I run q2r in the
6.2.1 version? I use q-shift, then q2r does not work, you know this. Please
tell me details
Best regards
Enamul Haque
