Dear Developer,
I am getting an error message during the dielectric calculation.

Dear Joydev,
actually, it is not clear what's happening here.
Anyway, your input file does not make much sense.
If you want to do an IP calculation you should use:

Code: Select all

Chimod= "IP"
Otherwise, if you aim to a TDDFT-ALDA calculation, you should raise the value of FxcGRLc and NGsBlkXd.
I will look anyway, why you get this error.

Dear Joydev,
can you also attach the pseudo-potential ?
I'll try to reproduce the error.
