Abstract:
We present a Lagrangian method for simulating incompressible
gases in 3 dimensions. Using the vorticity equation with Lagrangian
particles, we create, modify and delete vortices of varying
size in a manner that handles buoyancy, boundaries, viscosity and
collision with deformable objects using monopoles. Our method
scales linearly for parallel processing and provides user controls
at varying resolutions. We address common problems of particle based
vortex methods, and provide mathematical justification for
all terms. All implementation details are provided.
