'''FeatFlow''' (for "Finite Element Analysis Toolbox for Flow") is a free and open-source high-performance [[computational fluid dynamics]] [[Fortran]] CFD code solving the incompressible [[Navier–Stokes equations]] in two and three dimensions.

Unique for CFD and FEM codes, FeatFlow employs a [[finite element]] discretization with rotated non-conforming <math>\overset{\sim}{Q}_1Q_0</math> basis functions<ref>{{cite journal|url=http://doi.org/10.1002/num.1690080202 |title=Simple nonconforming quadrilateral Stokes element |journal=Numerical Methods for Partial Differential Equations |volume=8 |issue=2 |pages=97–111 |year=1992}}</ref> which coupled with a geometric [[Multigrid method|multigrid]] approach enables very high performance<ref>{{cite book|url=https://www.springer.com/us/book/9783642635731 |title=Efficient Solvers for Incompressible Flow Problems, Series: Lecture Notes in Computational Science and Engineering |volume=6 |publisher=Springer-Verlag |year=1999 |ISBN=978-3-642-58393-3}}</ref>. Several numerical benchmarking projects have compared FeatFlow in CFD benchmarks with other academic and commercial CFD codes such as [[OpenFOAM]], [[ANSYS CFX|CFX]], [[Comsol]], and [[ANSYS|Fluent]], where it has been shown that FeatFlow can be significantly faster and more efficient, computing a more accurate solution in less CPU time for some flows<ref>{{cite journal|url=http://www.inderscience.com/offer.php?id=48245 |title=Benchmark Computations of 3D Laminar Flow Around a Cylinder with CFX, OpenFOAM and FeatFlow |journal=International Journal of Computational Science and Engineering |volume=7 |issue=3 |pages=253–266 |year=2012}}</ref><ref>{{cite journal|url=http://doi.org/10.1504/IJCSE.2015.070993 |title= Evaluation of commercial and academic CFD codes for a two-phase flow benchmark test case |journal=International Journal of Computational Science and Engineering |volume=10 |issue=4 |pages=387–394 |year=2015}}</ref><ref>{{cite journal|url=http://www.mathematik.tu-dortmund.de/lsiii/cms/papers/FengKoesterZhang2005.pdf |title=Cylinder Flow Benchmark with Commercial Software Package - A Comparative Study |journal=Ergebnisberichte des Instituts für Angewandte Mathematik |volume=287 |year=2005}}</ref>.

Although FeatFlow is designed and can be used as a stand-alone CFD flow solver, a [[Matlab_CFD|MATLAB CFD]] and [[GNU Octave|Octave]] cross-platform [[GUI]] interface is also available. The [[FEATool|FEATool Multiphysics]]-FeatFlow GUI environment is fully integrated with [[CAD]], geometry, grid generation, as well as postprocessing and makes FeatFlow easier to learn and use <ref>{{cite web|url=https://medium.com/multiphysics/featflow-cfd-solver-gui-integration-with-matlab-b50cbd0545c7 |title=FeatFlow CFD solver GUI integration with MATLAB}}</ref>.
