SIESTA (computer program)


 * For other uses, see Siesta (disambiguation)

SIESTA (Spanish Initiative for Electronic Simulations with Thousands of Atoms) is an original method and a software implementation for performing electronic structure calculations and ab initio molecular dynamics simulations of molecules and solids.

It uses a density functional theory code that predicts the physical properties of a collection of atoms.

Properties that can be predicted using the code include Kohn-Sham band-structures, electron density, and Mulliken populations.
