Visualization of Q=0.01 isosurface coloured by the sensor function, which indicates the presence of sub-grid structures.

Simulation details: OpenFOAM v1812, 32x32x32 cells, 2nd order linear in space, 2nd order backward in time

The flow is cycling in a periodic domain, thereby no turbulent inlet condition need to be built. After the separation on the leeward side of the hill, a shear layer is formed which reattaches to the floor. This behavior is strongly affected by the turbulence model.
The video covers two throughflow-times at bulk velocity.

Simulation details: OpenFOAM v1812, 2nd order central in space, 2nd order backward in time, WALE turbulence model, 11.7M cells structured mesh (396x148x200)
