[Pw_forum] NaN in phonon

[Ezad Shojaee]

hi
i tried to perform ph.x by a grid and at the 10th point, i have NaN in the 
15th mode, so is seems that the code is in a cycle and does not continue
what should i do according to the long time it has take for the 9 points 
before?!!
what's the problem?
is there anyway to force the code to continue and use the interatomic force 
constants of other points ?
thanx for any hint
