Detailed Water With Coarse Grids: Combining Surface Meshes and Adaptive Discontinuous Galerkin

This method simulates liquids with new techniques that allow for fine details within a single regular grid cell. It adaptively applies more complex physical models in cells where more detail is needed, without the complexity of subdividing the grid.

Blending Liquids

A semi-automatic method for matching two existing liquid animations, which is used to create new fluid motion that plausibly interpolates the input. The technique can be used to instantly create hundreds of new simulations, or to interactively explore complex parameter spaces.

Augmented MPM for Phase-Change and Varied Materials

A large number of materials can be simulated using this generalized material point solver that handles elasto-plastic and nearly-incompressible materials as well as phase transitions.

From Capture to Simulation - Connecting Forward and Inverse Problems in Fluids

This paper explores the connection between fluid capture, simulation, and proximal methods. It shows equivalence between key operations that allows incompressible flow problems to be solved naturally in a proximal framework, making applications such as velocity estimation from capture, capture super-resolution, and guided simulation straightforward to solve in an extensible, efficient framework.

Smoke Rings From Smoke

An algorithm that extracts vortex filaments (“smoke rings”) from a given 3D velocity field. This is useful for visualization, analysis of measured flows, hybrid simulation methods, and sparse representations. The method requires only sparse linear algebra and scales well with grid size.
