Schrödingers Smoke ( SIGGRAPH 2016)

We describe a new approach for the purely Eulerian simulation of incompressible fluids. In it, the fluid state is represented by a ℂvalued wave function evolving under the Schrödinger equation subject to incompressibility constraints. The underlying dynamical system is Hamiltonian and governed by the kinetic energy of the fluid together with an energy of LandauLifshitz type. The latter ensures that dynamics due to thin vortical structures, all important for visual simulation, are faithfully reproduced. T
