hi
sorry if it is a silly question
if we used a grid for calculating  phonon dispersion and we find that it 
is'nt sufficient, what should we do? defining another grid ( with more 
points ) and performing for all of it again?!
is there any way to add some new points information to the previous grid ?
thanx
