Physics-based Animation of Fluids and Deformable Solids

Physics-based animation uses ideas from applied and basic physics to computationally model the simulation of natural phenomena and characters.

We look at fluid flow and how it interacts with solids. We model how it seeps into those solids and wets them. This lets us study the wetting of clothes and rocks.

In another work, we create a computational model for fracture and look at how solids break on impact and under various kinds of loading. This is further extended to study how we can control these fracture surface under precise deformation and cutting operations, letting us devise simulations for virtual surgery.

We combine the above models for wetting and deformable solids to create material models that change their elastic properties on wetting - this has applications in the modelling of clay like matertials that can enable virtual sculpting.
