Hi Enrico,

Yes, you're right. The variables ecut and k-mesh are somehow dependent.
However, you can optimize both parameters independently. I suggest you to
choose first a dense enough k-mesh in the reciprocal space taking into
consideration the properties you want to study: DOS, band structure,
electro-phonon coupling, vibrational frequencies, etc, then test the
convergence regarding ecut.

Hope I could help.

Cheers
