Stable version - Siesta 3.2 (patch level 5) (ChangeLog) (Manual) - Siesta 3.2 (Mar 28, 2013) - Older version: Siesta 3.1 Development version It might be unstable, as new features are added at a faster pace. See the Docs/CHANGES file for more information.This version includes the van der Waals functional, the new load-balancing code for real-space grid operations, and other improvements and bug fixes.Recent development snapshots include significant enhancements to TranSiesta/TBTrans. TranSiesta users are encouraged to test the recent snapshots. Please read the file Docs/TranSiestaUpdate.pdf, as well as the manual, to get a primer on the new features and things to watch out for and explore in the new code.We welcome bug reports (see the file Docs/REPORTING_BUGS). - Most recent development snapshot: siesta-trunk-462 (May 29, 2014). (ChangeLog from 458) (Reference Manual)(Includes new functionals and other fixes.) - Older development snapshot: siesta-trunk-458 (March 13, 2014). (ChangeLog from 454)(Includes an experimental charge-density-mixing scheme and other fixes.) - Older development snapshot: siesta-trunk-454 (January 31, 2014). (ChangeLog)(Includes an experimental orbital-minimization method without localization as an alternative to diagonalization, new mixing options, and other fixes.)NOTE: The grid functions (charge densities, potentials, etc) are in double precision by default in the development version (as of trunk-322). The 'phi' array that holds the values of the basis orbitals on the real-space grid is kept in single precision. Please take this into account if you compare the results of development-version runs with those of siesta-3.X runs. See the manual in both versions for more information.For more information on the load-balancing changes, see: C. F. Sanz-Navarro, R. Grima, A. Garcia, E. A. Bea, A. Soba, J.M. Cela, and P. Ordejon, Theoretical Chemistry Accounts 128, 825-833 (2011). DOI: 10.1007/s00214-010-0816-5 Older 2.X version (not maintained any more) - Siesta 2.0.2 Other versions of Siesta - SIESTA-PEXSI (Dec. 2014) - Development version which includes the DFT+U functionality: siesta-ldau-308 (Feb. 2010)(Note that this version is several patches behind the main development. We are working towards merging the DFT+U code into the main version.) - Older version compatible with the Smeagol program: siesta-1.3f1 (Feb. 2004) .............................................................................................................................................................................All the bestDJAADI Soumaia
