Zeynab,

and one more thing, in order to check that the TranSIESTA calculation restarts properly, you should look at whether the energies, convergence of the density matrix and Fermi energy for the first SCF steps are very close to those of the last SCF steps of your previous run. The SCF counter simply starts from 1 again as Nick points out.

Hi Zeynab,

the *.TSHS files are built in a previous stage, during the Electrodes calculations (which is actually a pure SIESTA calculation with a high number of k-points in the transport direction), and then used when the Scattering Region calculation starts to describe the electrodes, but it is true that they do not change anymore at this last stage.

regards,

Carlos

In fact, TSHS file isn't used for a continuation run.

A continuation run does not know what the previous runs Scf count is, so it starts over.
If it says it has read in the TSDE file, then it is a continuation run.

So I would guess nothing is wrong and it actually behaves as expected. :)

In addition, and what really makes a specific TranSIESTA restarting, you must check that you have the *.TSHS and *.TSDE files from the previous run in the directory where you are going to restart TranSIESTA. By the way, TS.SaveHS is true by default, so you should find the *.TSHS from the previous run unless you set up TS.SaveHS false previously.

If both electrodes are identical structures, the same .*.TSHS can be used to describe both. In general, however, the electrodes can be different and therefore you will have two different *.TSHS files; one for the left electrode and and another for the right electrode.

It is equivalent to the *.DM file for SIESTA (i.e., density matrix with periodic boundary conditions in all directions and no voltage), but the density and energy matrix stored in *.TSDE has open boundary conditions and bias potential.
