Fast Grid-Free Surface Tracking

This paper proposes a new surface-tracking method. Its main advantage over existing approaches is that it is both completely grid free and fast which makes it ideal for use in large unbounded domains. Its applications are demonstated in Eulerian and Lagrangian fluid simulations, solid simulation, and mesh manipulation.

High-Resolution Brittle Fracture Simulation With Boundary Elements

A method for simulating brittle fractures using a boundary-element method and Lagrangian crack-front propagation. This method is efficient, and it produces highly detailed fracture surfaces by combining a high-resolution crack-front, a coarse computational mesh, and detailed material toughness models.
