Dear Abinit Users?
I tried to investigate convergence according to different k-points mesh.
  I used next k-points mesh:
   (2 k-points) - 1 1 4 
   (3 k-points) - 1 1 6 
   (4 k-points) - 1 1 8 
   (5 k-points) - 1 1 10 
   (6 k-points) - 1 1 12 
   (8 k-points) - 1 1 16
 thre are my result:
k              Etot (Ha)                       Etot (eV)
2       -144.780880485148       -3939.68820712992
3       -144.788626129349       -3939.89897683245
4       -144.780626293347       -3939.68129021906
5       -144.784690801234       -3939.79189110600
6       -144.784609401319       -3939.78967610162
8       -144.784449706748       -3939.78533059123 

  I got strange behavior for 2, 3, 4 k- points. It just jumps up and down.
  Why does it jump? I only changed ngkpt in input files. 
    
  Thank you in advance!
    Yaroslav!
