This model example studies stationary and laminar flow around a cylindrical obstacle in a channel with Re=20. The computed pressure drop, and drag and lift coefficients are compared with established benchmark references to assert the accuracy of the simulation.

Although not featured in this tutorial, in addition to the built-in stationary, non-linear, and transient flow solvers, FEATool also features built-in GUI interfaces for the FEniCS and OpenFOAM CFD solvers. A benchmark study has been made which compares OpenFOAM, FEniCS and FEATool for this fluid flow test case and illustrates how well ones can perform CFD bencmark and simulations in Matlab.

The model is also available in the tutorial and examples section of the FEATool Multiphysics User's Guide:
