I just followed the tutorial of Born effective charge. According to that,
we have to initialize the calculation for the unchanged material. Then we
have to change the position and den we have to initialize the electron
density only i.e. ''x dstart''. They have mentioned not to rerun init_lapw
. So
One more thing: I dont know how to calculate born effective charge. But you
see your new struct file there are 6 position for Bi, 6 position for O and
2 for Fe. So new composition is 3:1:3 while in original it is 1:1:3.
So look on the new struct file, how you changing position of Bi and why rmt

Did you see any error in x nn?
I am getting nn error in your Bi-changed structure, see below:

1.d-5, 20)]

Dear Dr Bhamu,
Actually I have already searched for that. But as I am changing the
position of an atom, I guess the symmetry breaks and the error comes. With
the struct file with unchanged atomic position, it runs fine.
Dear Oleg Rubel,
Here I am attaching the two struct files used in “initial”
I can verify the problem.
However, I could not find a fix quickly. Since I'm very busy in the next
2 weeks, it may take some time to debug this completely.
As mentioned before, when SO does not change symmetry (you can see this
in outsymso file if all operations are either type A or B), you c
Would it be possible to attach the structure files used in “initial”
calculation and after the displacement is introduced?
Thank you

Some time ago I got same error and by compiling SRC_hf agin I overcome the
error.

Dear Users,
I am trying to calculate born effective charge for Bi atom in BiFeO3. I
followed the tutorial for GaAs as BiFeO3 is having non orthogonal lattice
vectors. I used berrypi with -s option as it consists of magnetic ion. But
after changing the position of Bi atom by 0.001, when I put the c
For sure there can be examples where the old min_lapw is faster, but
experience is that usually run -min is faster than min_lapw.
I have a different opinion about constraining positions. I'm using this
very frequently and have no problems with it.
But: don't be surprised if on these constrained
Dear Seongiae,
my two cents on this:
Physics in general is about modeling some situation with as few and as
simple assumptions, approximations and parameters as possible.
If the model works, that is if the model behaves similar to the real
thing, fine. As you observed: The confidence in the m
It's is not impossible, but my intuition is that it is more likely with
hard problems involving d or f electrons.
And, yes, I don't think it is good to fix the bulk, and don't expect it to
save time.

If you omit -orb, then +U will not be applied.

Hi,
Yes, as you said, NE in case.in2 was not properly copied in
case.in2eece. This is due to a bug in the script runeece_lapw.
In runeece_lapw, replace these two lines

echo $emin $nocut >> $file.in2${complex}eece

Yes, of course. This is exactly the way to do it.
