[Pw_forum] phonon calculation with dispersion corrections

Dear everyone:

I have a question on phonon calculation with dispersion corrections.

In order to include the (semi-empirical) vdW correction into phonon
I first performed the scf calculation with the command "vdw_corr =
then I performed the phonon calculation with PH.x.

But, I didn't found any command in the input lists of the phonon program,
Also, in the output of PH.x, there is no message about the vdW correction.

If the scf calculation included the vdW corrections, does the phonon
calculation automatically (without any command about vdW) include the vdW
correction in the phonon calculation?
