The example below is a tank with inflow at the surface and outflow close to the tank floor. Four series of particles are released from four positions at the inlet. The four series are shown in four colours. When particles reach the outflow boundary, they are instantly inserted back into the inflow bounday where they started. This gives a continous simulation.
