Flow around a cylinder - Adaptive Mesh Refinement (AMR) - Fluid Mechanics - OpenFOAM 2112

This video shows the implementation of Adaptive Mesh Refinement (AMR) technique on OpenFOAM 2112 to solve the case a flow around a cylinder, generating a Von Karman vortex street.

The mesh is dynamically refined when the magnitude of the velocity gradient exceeds 30 1/s, and is unrefined when it goes below 10 1/s.

The source code for the case is available at:

github.com/nicolasbadano/GradientAMR

The Reynolds number of the flow is Re=220.
