[Pw_forum] grid without symmetrical problem

[Ezad Shojaee]

hi
yes, the grid must have the symmetries of the system,  i have tried some 
grids & non of them had the symmetries needed, how should i find the 
suitable grid according to my system not to have the error at the end of the 
phonon calculation?! is there any formal way?
thanx
