Permeable and Absorbent Materials in Fluid Simulations
Nathan Andrysco, Matt Brisbin · 2008
The interaction between fluids and materials is an important part of fluid simulations. Many research efforts have been performed to incorporate the coupling between solid objects and fluids. However, the interaction of fluids with permeable materials has been neglected. We present a solution to fluid simulations that allows for the simulation of porous and absorbent materials. Our extension is based on well known physical laws that describe the interaction of fluid with permeable objects. These laws can easily be integrated into any semi-Lagrangian based solver which enable fluid simulations to have effects such as water flowing through soil or a towel soaking up spilled liquid on a kitchen counter.
