Jonas,
What do you mean by "MKL libraries"?
Supposing you are trying to compile Siesta 3.0, check the directory Src/Sys.
It has many examples of arch.make files which you can use directly or adapt,
if necessary. Also, do a search in the list archives - loads of arch.make's
have been posted in the

I have problems compiling. Regardless what I do (MKL libraries or run

Dear all,
This is a bug that has been corrected in an updated 3.0 package that
will be distributed in the next few days.
In the meantime, you can easily fix your copy of Siesta by applying
the following patch:

Dear Martin Zoloff
Thank you for the reply.
I have asked some of my friends to test the ExternalElectricField block using
siesta-3.0b compiled in different clustors, the same results are obtained. It
should result from the debug of this beta version.

Not really. The dispersion in z-direction has nothing to do
with the thickness of your sl
Thank you.

Ian,
I guess what Andrei meant is that your cell should be, in the limit,
infinite along the z direction. I would guess that when he speaks of layers,
it is related to the length of the z axis in units of layer thickness. In
the limit of infinite z-axis length, your BZ will be 2-dimensional and al
Thanks for the reply. Taking the limit of what you've said, Andrei -
if you want a really slow dispersion in the k_z direction, it would
presumably be best to work with a thin (i.e zero thickness) slab. This
would mean the dispersion in the k_z direction should be infinitely
slow - right?

First of all, you have to build a supercell without vacuum, for your surface

Second, you must calculate the band-structe

A PhD position is opened at the Université P. & M. Curie (UPMC, Paris

using first-principles molecular dynamics simulations (see attached

We are seeking for a solid-state physicist or a

With a cluster it is not necessary to use k-points, one just needs the cell
to be sufficiently large to make interactions between images neglectable.

Hi Daniel,
If it is a cluster (no periodic conditions), is it
necessary to use use plenty of kpoints?

Subject: RE: [SIESTA-L] Is the siesta
SIESTA is capable of your (computationally intensive) problem. When working
with metals,
be sure to use a large MeshCutoff ( > 350 Ry.) as well of plenty of k-points.
If you have a lot of
k-points, then you can use the Diag.ParallelOverK option.

Dear all,
I intend to calculate the magnetic property of a cluster of metal with about
one thousand atoms implanted a isolated Fe impurity. But I have no idea
whether the siesta is suitable for this metallic system. Please give me some
suggestions about this.
Thank you in advance.

Dear tansiesta users:
Who can tell me what are the .LDOS and .RDOS,they seem to also DOS.
How can I get the LDOS(local partial DOS) after a calculation.

Dear friends!
I`m just starting make a computation in TranSiesta.
I have three very important for myself questions.
1.) I don`t understand physical properties of such parameters:
TS.ComplexContour.NPoles, TS.ComplexContour.NCircle, TS.ComplexContour.NLine,
TS.NumUsedAtomsLeft, TS.ReplicateA1Le
