'''SIESTA''' ('''Spanish Initiative for Electronic Simulations with Thousands of Atoms''') is an original method and aits softwarecomputer program implementation, to forperform performingefficient [[electronic structure]] calculations and [[ab initio]] [[molecular dynamics]] simulations of [[molecules]] and solids. SIESTA's efficiency stems from the use of strictly localized basis sets and from the implementation of linear-scaling algorithms which can be applied to suitable systems. A very important feature of the code is that its accuracy and cost can be tuned in a wide range, from quick exploratory calculations to highly accurate simulations matching the quality of other approaches, such as plane-wave and all-electron methods.
SIESTA is the [[backronym]] of Spanish Initiative for Electronic Simulations with Thousands of Atoms.
Starting in the Spring of 2016, with the 4.0 version, SIESTA is released under the terms of the [[GPL]] open-source license. Source packages and access to the development versions can be obtained from the [https://launchpad.net/siesta new development and distribution platform].▼
