Simulation with a particle system made with Blender. We used three issuers 20.000 spherical particles in each, issued continuously for 200 frames.
Added a vortex hard “4” in the center to generate the system dynamics.
A map does not absorb collision energy of the particles complete the stage.
A vortex is rotating turbulent flow spiral closed current paths. Vortex can be considered as any kind of circular or rotary flow having vorticity. Vorticity is a mathematical concept used in fluid dynamics that can be related to the amount of movement or rotation of a fluid. Vorticity is defined as the flow per unit area at a point of flow.(W)
