Dear siesta users,
as far as I understand the only tool capable to plot wave functions in
Siesta is Denchar.
Unfortunately I got following error during compilation and cannot proceed.
This error is mentioned in mailing list archive, but I found no solution
published.
Please, help...

Dear Siesta users,
in page http://fisica.ehu.es/ag/siesta-extra/release.notes_2.0.2
there is stntence To support gfortran, the f2kcli.F90 program has been
updated.
But when somebody try to compile denchar with gfortran
immediatly receives an error
/home/zhachuk/siesta-2.0.1/Src/f2kcli.F90:212:
Dear siesta users,
while trying to compile denchar program I am getting this error message
(below).
Does anybody know how to fix it?
Regards

Dear Siesta users,
I had Sr atom (2 valence s-electrons) with DZP basis set.
This results in following basis:
%block PAO.Basis # Define Basis set
Sr-adatom 1# Species label, number of l-shells
n=5 0 2 P 1 # n, l, Nzeta,
Dear Andrei,
this seems to be a too loosely defined question;
will be Siesta accurate enough with which basis, cutoffs etc.?
basis set DZP
mesh cutoff 200 Ry
I did test calculations for Si(100) (unreconstructed and unrelaxed) surface
energy in Siesta, the Esurf is very
close to published values
Dear SIESTA users,
I am trying to make constant-height image of Si(111)-7x7 (not rectangular
unit cell).
After running plstm I got file with 0 bytes. The output of plstm is below.
The values of cell vectors are strange. What can be the problem?

Dear siesta users,
when I try to specify basis size TZDP I get the following error message:
size_name: incorrect basis-size option specified, active options are:
SZ, SZP, DZ, DZP, and STANDARD
How can I activate TZDP? It is explicitly mentioned in
The Siesta method for ab initio order-N
Dear siesta users,
can anybody explain me what the Maximum dynamic memory allocated means
just before the self-consistency cycle begins?
In parallel calculations (ParallelOverK, k-points: 4 4 1) when I use
1 CPU Maximum dynamic memory allocated=158 MB
2 CPU Maximum dynamic memory
Dear SIESTA users,
can you help me to write request for resources
for parallel run. It looks like when this request
is incorrect the job stops.
We are using PBS Pro 9.2 system.
The request string looks like this:
#PBS -l select=3:ncpus=3:mpiprocs=3:mem=6GB
The system I am studying is Si slab
Dear SIESTA users,
recently I found a paper Phys. Rev. Lett. 94 (2005) 056103
which describe new effective method to simulate realistic STM images.
It is not just LDOS plot, the authors calculate wave fucntions of tip and
surface independently
and then simulate the current, assuming that tip
You just set the H atom in the direction of Si bond at the distance,
corresponding to the length of Si-H bond.
As I remember it is approximately 1.5 Angstrom. Keep the coordinates of H
atom and Si atom connected to it
fixed during structure optimization. You don't need to relax them.

Dear SIESTA users,
I have difficulties trying to converge calculation with respect to
PAO.EnergyShift.
The system is 8 layers silicon slab, hydrogenated.
The total energy varies strongly with PAO.EnergyShift parameter:
PAO.EnergyShift Etot
300 meV -21007.7361 eV
250 meV
Dear SIESTA users,
I have problem with specifying different basis sets for different atoms.
The manual is not clear in this respect.
Could you please show me the correct input for fdf file?
Kind regards
Ruslan
P.S. Below are list of files in folder, error message and my fdf file.

Dear SIESTA users,
I need to model STM image of clean Si surface, i.e. to get LDOS.
All important calculations I did in AIMPRO code and now I need only STM
image,
so the calculation does not need to be very accurate.
I moved to SIESTA since AIMPRO has no STM utility.
But I am new to SIESTA and
Dear Chol-Jun Yu,
the method is explained in detail in:
A.A. Stekolnikov, J. Furthmueller, and F. Bechstedt, Phys. Rev. B 65, 115318
(2002).
Try to read this first.
Kind regards

Dear all,
could anyone teach me how to calculate the surface
Dear SIESTA users,
could you please explain me the sense of MeshCutoff parameter in SIESTA?
The manual is short in this respect:
-
MeshCutoff: Defines the equivalent plane wave cutoff for the grid.
Default value: 100 Ry
-
I can understand energy cutoff parameter in
Dear SIESTA users,
how to generate output for multiple LDOS, each one with its own Uinitial
and Ufinal?
The system is quite large (about 200 Si atoms) and it takes a long time for
SCF to get solution.
And then I got only one LDOS for single Uinitial and Ufinal values.
Should I save some values
Dear SIESTA users,
I am using OpenSUSE Linux 10.3 and installed following packages to compile
SIESTA utilities:
