An overview of both free and commercial CFD software. Here you will find short descriptions of codes along with links to resources.

Note to contributers: Please try to keep descriptions short and to the point (approximately 200 words) and avoid long lists of features or capabilities. Also keep in mind that all contributions are considered to be released under the GNU Free Documentation License 1.2 (see Project:Copyrights for details). Also note that all information should be verifiable and objective truths that also competitors to the code in question will agree upon. This is especially important if you are an employee of the company selling the code. See the CFD-Wiki:Policy for further information.
