Intel reports a bug with version 8.1 , with version 8.0 produce no problems.
Hi,
I recently compile siesta 1.3, with MPI support (blacs, scalapack,
mpi libraries standard comes from debian 3.1), but when i run the program
with mpirun , siesta says it a parallel version and freeze mpirun:

Dear SIESTA users,
I am actually in trouble with SIESTA, Indeed this is possible
I am using SIESTA in Ab-Initio MD simulations, on an IBM blade Center

My jobs are running successfuly, but only using 1procs/node this is

Dear Mousumi,
in addition to what María and Aleksei said a comment on your input file.
You can use SZ to see whether the phonon calculation works or not.
However, don't expect good values for the calculated frequencies with this
poor basis. You want to use DZP with a 50-100meV EnergyShift for

Dear All,
I want to present a distribution of the valence electron density for
CNT.
This is my first time to use SIESA. How can I do that? Is there any
program for that?
Please let me know.
With Best Regards

Dear Mousumi,
What you need is a supercell, which you can create with fcbuild or by
hand. Each unit cell vector must be repeated an odd number of times,
for example 3x3x3.
Then tell siesta to displace only the atoms of one unit
cell (use MD.FCfirst and MD.FClast). The condition for a good dispersi
Dear Siesta users and developers,
We would like to see the pressure -dependence of elastic constansts on some
semiconductors.But for this, firstly we need to calculate the pressure
-dependence of lattice constants using Siesta.How can we enter the pressure to
see the effect on energy ?
Thanks

Dear Maria, Steffi, and all,
Thank you very much for your response. I want to
calculate the general dispersion relation for my system;
not only the phonon modes at Gamma. So, for this, how to
use "vibra package"?
Secondly, I have seen the output file. The phon
Hi Mousumi,
the atoms are moved into positive and negativ directions during the FC
run. This double the number of elements in the force constant file (pos
and neg are averaged during the vibra run).
Just a warning: with the unit cell you can only calculate the phonons at
Gamma. If you want dispe
Dear Mousumi,
your calculation is right, just that siesta calculates for positive AND
negative displacements (see output file) which are later averaged by
vibrator. So you have:
2 atoms x 3 degrees of freedom x 2 signs = 72

In order to get the dynamical matrix, I use " MD.TypeOfRun FC "

I have done some simulation of transition metal dimer . The
