MATLAB CFD Simulation Tutorial - Flow Around a Cylinder | FEATool Multiphysics
This tutorial and model example illustrates how fast and easy it is to set up and solve computational fluid dynamics (CFD) flow problems with the FEATool Multiphysics simulation toolbox https://www.featool.com
Although not featured in this tutorial, in addition to the built-in stationary, non-linear, and transient flow and multiphysics solvers, FEATool also features built-in and easy one-click GUI interfaces for the OpenFOAM, SU2, and FEniCS solvers.
The example examines stationary and laminar flow around a cylindrical obstacle in a channel with a Reynolds number of 20. The computed pressure drop, and drag and lift coefficients are compared with established benchmark references to assert the accuracy of the simulation [1,2].
More details, multiphysics simulation toolbox, presented simulation model example, are all free to download from the FEATool homepage and in the tutorial section of the FEATool Multiphysics User's Guide https://www.featool.com/doc/tutorials...
