Dear admin and vasp users

I think density functional perturbation theory is a major improvement in the vasp code. I was wondering why there is so few information about it in the manual except "switch IBRION to 7 or 8" and a few other keywords.

I performed a linear response calculation on a simple material and I now have a DYNMAT file which is not even mentioned in the manual. Or maybe I did not search well enough.

Could you please let me know if there is more practical information on the use of DFPT in vasp?

Thanks
