Hi all,

I've a problem when I do the Abinit's tutorial lesson 4.3 *The 
convergence study with respect to both number of k points AND broadening 
factor (tsmear).*.  The following is my input file:

--------------------------
ndtset   16     udtset  4  4

ngkpt1?   2  2  2  
ngkpt2?   4  4  4  
ngkpt3?   6  6  6  
ngkpt4?   8  8  8

tsmear?2  0.02

I want to know the following two things:

1.  If the parameter *udtset* is used, how can I know a 
parameter controled by it will be performed in the inner loop or outer 
loop.  For example, in this case, the ngkpt or the tsmear will be 
done in the inner loop and the other in the outer loop?

2.  How can I know which parameter should be put into the inner loop or 
the outer loop when I use the *udtset* to control them?  In my case, 
should I use the ngkpt or the tsmear as the inner loop and the other as 
the outer loop parameter?

Thanks in advance.
