Dear wien2k users:
Thank you for kind replies from Dr. Rocquefelte and Dr. Cottenier. When
we begin to start wien2k for zinc oxide, the R0 value for zinc is set to
0.0001. This is the problem. We asked the installation of wien2k to
computer company, and I cannot know how the R0 value is

When you create your structure file you should specify the correct name
of the atoms (Zn, O) and not the atomic number (Z).
This problem has been reported many times and leads to incorrect R0 values.
I recommend you to regenerate the structure file using on of these two
strategy:
1/ by hand
You already got the answer previously:
The line:
echo $WIENROOT run_lapw -p -NI -ec .001 -I
does not execute anything.
Try out such a line in a terminal window.
If you want to use a supercomputer, you need to learn some basic Linux.
Who wrote the nice script ? He should be able to

If you start from a ferromagnetic situation, you will converge towards a
ferromagnetic state (I never encounter other situations).
However, it does not mean that you will find the global minimum in terms
of magnetic structure.
It simply means that you have converged the electronic density
Actually I have come across several cases where I started with a
ferromagnetic state and it converged to non-magnetic or even
antiferromagnetic, or the opposite. It does take a long time for it to
change, so as Xavier says it is probably better to start from
different minima.
Note: the atomic

and not to forget, if the symmetry of the structure you use does not allow for
antiferromagnetism then you will not find it.
NOTE: Symmetry is everything
