ABINIT Discussion Forums

Hi guys, I am newbie here

I have problem with my work, i failed compiling abinit toptic_1 with this input files:

#First dataset : SC run with kpoints in the IBZ
iscf1 3
nband1 32
nstep1 25
kptopt1 1
nbdbuf1 0
prtden1 1 getden1 0 getwfk1 0 ! Usual file handling data

#Second dataset : NSC run with large number of bands, and points in the IBZ
iscf2 -2
nband2 32 ! This number of bands might be too low for non-linear optics and real part of linear optics
nstep2 25
kptopt2 1
getwfk2 1 getden2 1 ! Usual file handling data

#Third dataset : NSC run with large number of bands, and points in the the full BZ
iscf3 -2
nband3 32 ! This number of bands might be too low for non-linear optics and real part of linear optics
nstep3 25
kptopt3 3
getwfk3 2 getden3 1 ! Usual file handling data


#Fourth dataset : ddk response function along axis 1
iscf4 -3
nband4 32 ! This number of bands might be too low for non-linear optics and real part of linear optics
