 Dear all
 
  I would like to perform a scf calculation with small kpoints,and then do nonscf calculation 

with a large kpoints. So my questions is :

1 what to do  when I want a nonscf calculation with a larger  kpoints.

2 when I only do scf calculation with too large kpoins.

The warning is as followed:

================================================== 

 NUMBER OF K-POINTS IN WHOLE CELL: (0 allows to specify 3 divisions of G)
 length of reciprocal lattic vectors:   1.422   1.422   1.422  66.943  66.943  66.943
 nmax too large in ord1.f, set indexm at least      1724976
nmax, redimension ord1.f
1.692u 0.504s 0:02.19 100.0%    0+0k 0+0io 0pf+0w
===============================================

So I recomplier the order1.f , however,I still failed to use as large as 82 82 82 kpoints.

Actually I'm confused by the 'nmax'. Can you explain it,please? 

 
Thanks you
