SIESTA is both a method and its computer program
implementation, to perform efficient 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.
