Fluid Flow: Lagrangian Particle Representation


In this movie, we place 10,000 Lagrangian matter tracers representing fluid elements. The initial distribution of Lagrangian tracers is proportional to the initial mass density. We then calculate the trajectories of the tracers by integrating the fluid velocities. The particles are color-coded according to the fluid density at their current location.

Note that the fluid elements are tied to the magnetic fields.  Also, the core collapse and formation of the ambient disk is evident.
