'''code_saturne''' is a general-purpose [[computational fluid dynamics]] free computer [[software suite|software package]]. Developed since 1997 at [[Électricité de France]] R&D, code_saturne is distributed under the [[GNU GPL]] licence.
It is based on a co-located [[Finite volume method|finite-volume]] approach that accepts meshes with any type of cell (tetrahedral, hexahedral, prismatic, pyramidal, polyhedral...) and any type of grid structure (unstructured, block structured, hybrid, conforming or with hanging nodes...).

Its basic capabilities enable the handling of either incompressible or expandable flows with or without heat transfer and turbulence (mixing length, 2-equation models, v2f, [[Reynolds stresses|Reynolds stress models]], [[Large eddy simulation]]...).
Dedicated modules are available for specific physics such as [[thermal radiation|radiative heat transfer]], [[combustion]] (gas, coal, ...), magneto-hydro dynamics, [[compressible flow]]s, [[Multiphase flow|two-phase flows]] ([[Lagrangian and Eulerian coordinates|Euler-Lagrange approach]] with two-way coupling), extensions to specific applications (e.g. for atmospheric environment).

The current production version is 8.0 (2023-06-30). <ref>{{cite web | url=https://www.code-saturne.org/cms/web/news/codesaturne-80-released | title=Code_saturne 8.0 released | code_saturne }}</ref>

== code saturne install ==

code_saturne may be installed on a [[Linux]] or other [[Unix-like]] system by downloading and building it. No system files are changed, so administrator privileges are not required if the code is installed in a user's directory. Packages for code_saturne are also available on [[Debian]] and [[Ubuntu (operating system)|Ubuntu]]. Alternatively, CAE Linux (latest version [https://www.caelinux.com/CMS3/index.php/articles/70-/59-caelinux-2018-is-released]), includes code_saturne pre-installed.

The code also works well in the Windows subsystem for Linux.

== Interoperability ==

code saturne supports multiple mesh formats. The following formats, from open source or commercial tools, are currently supported by Code Saturne:
