This 2D case of vortex shedding in laminar cross-flow demonstrates the concept of recurrence. This is a bit work-in-progress: please check whether this tutorial runs with the recurrence model and tools of CFDEMcoupling, namely rStatAnalysis. The simulation roughly goes through three stages: * The initial solution computed by potentialFoam * A period of symmetric, steady-state flow * Finally, periodic vortex shedding These three stages are clearly visible in the recurrence plot. * We see how not one of the later velocity fields is similar to the initial one * We see the intermediate stage with a symmetric flow field * We see the periodic vortex shedding
