FLIP Fluids as a Bi-directional Fuel Source in a Volumetric Fluid Simulation

ABSTRACT

We present a fast and flexible technique for creating Pyro simulations directly from and coupled with FLIP simulations for fuel. A typical Pyro simulation involves numerous ways to generate fuel but mostly as an input exclusively into the Pyro simulation not as a coupled partner into the simulation. None of the characteristics of the fuel and specifically the reaction of the fuel consumption is considered in a traditional Pyro simulation. We strived to create this relationship in a coupled simulation. This introduced shared fuel, divergence, and velocity data. All this sharing creates a more realistic simulation with little artificial initial velocity.
