Hi Nancy,
What version of Siesta are you using ? as far as I know dealing with
fractionally charges atoms is not possible in the distributed versions of
SIESTA ?.
Cheers,
Imad

Dear Denis,
Let me coment a bit your last message. I am not really aware about the specific
system that you are treating. However, as far as I have understood from the
massage, you are treating a system involving aromatic molecules. Note that the
source of you problem is related to the shortcom
hanges.
So how to keep the volume constant. i.e. from which option in fdf file to
streach and compress the crystal...
Kindly guide me

is applying particular strains that keep the volume constant !!! but the

Dear SIESTA users,
Is there someone who can share his Si and Fe : GGA-pseudopotentials !!
Best wishes,

I think there a small confusion !! If I well understood the primary mail :

Hi Bupul,
That means that your cell is under pressure !!
So you should, if its necessary (that depends on the problem you are dealing
with !!), to perform variable cell calculation,
Where you can choose the target pressure !! (enough small)

Hi Mousumi,
Before all, try to glance on the /src/sys directory
you should find an MPI mekefile that fit your
platform.
Hence, you can compile SIESTA (With the MPI makefile),
like you have done it in the serial version !!!
Best wishes

Dear SIESTA users,
I join my voice to Jan !!, And hope to get an answer to his question !!!
I posted it many times to the list by unfortunately no answer I got !!!

Dear siesta users and developpers,
Is there one who got experience of dealing with pseudo-hydrogen atomes (or
fractionaly charged atoms) !!! in SIESTA?
As I am investigating GaN surfases, I need to saturate some dangling bonds with
pseudohydrogens atomes of charge : 1.25e and 0.75e.

Dear Siesta users,
I am trying to investigate some GaN surfaces. For that I need to deal with
pseudohydrogens atoms (with fractional charges: 1.25e, 0.75e).
I would like to know if it is possible to generate pseudo potentials of these
atomes with ATOM code !!!
And doses sisesta can deal with fra
Hi Eduardo,
thank you a lot !! things seem to gone right !!
but I dont understand, why in page 17 of the siesta manual, for oxygen the polarized orbital seem to be counted in the begining of the block : [ O 2 nodes 1.0] !!
