WebSince this model is primarily intended for high-density crowds, I begin with this continuum represen- tation, similar to the Fluid Implicit Particle (FLIP) approach [Brackbill and Ruppel, 1986]. In the continuum formulation, the crowd state is defined in terms of two properties, den- sity ρ (people per m2) and current velocity v.
