screening calculation
Posted: Fri Jun 25, 2010 2:37 am
Dear Abinitors,
I want to do gw calculation for graphene nanoribbons and I see that the SCF and kss steps have been completed. But it has error as following when I do the screening calculation.
size_goed_fft : ERROR-
nbest = 65537
is larger than any allowable FFT
I can not understand what this error comes from. Does anyone have any suggestion for this? Thanks so much!
Best regards,
Xueping Jiang
