Hi,
Wich version of Abinit are you using ? Recent versions can stand much larger FFT grids (up to ~65000). May be upgrading to a newer version of Abinit would help ?

Dear All,
When I do the screening calculation in the GW calculation without using
the plasmon pole model, I get the following error:
......
timing point number 20
-cpu time = 0.02 seconds
-real time = 0.06 seconds
setmesh: npwwfn = 6043 ; Max (m1,m2,m3) = 11 11 11
setmesh: npweps/npwsigx = 2801 ; Max (mm1,mm2,mm3) = 10 10 10
addshell = 2
setmesh: using method 1 with aliasing_factor = 1
setmesh : finding a FFT mesh compatible with all the symmetries
setmesh : divisor mesh119119119
sizefft : ERROR-
nbest = 2049
is larger than any allowable FFT
leave_new : decision taken to exit ...
It seems related to the FFT grid. But when I decrease the cutoff
energies, I always get the same error. So, how to solve this problem,
please?
Thank you very much!
