I have a problem regarding response function phonon dispersion calculation for a wurtzite crystal.
I want to use a 443 grid for the q-points.
When I generate the kgrid with 443 and the shifts
0.5 0.5 0.5
0.5 0 0
0 0.5 0
0 0 0.5
abinit transforms it into
kptrlatt 8 0 0 0 8 0 -4 -4 3 .
The calculation runs through, but when i want to merge the ddb's
mrgddb gives an error. (I guess its because the number of kpoints at Gamma is not equal half the number of k-points at the other points?)
Can someone give me a hint on how to generate a good q-point grid?
Thanks
Marcel
