ElastoMonolith: A monolithic optimization-based liquid solver for contact-aware elastic-solid coupling
Takahashi, Tetsuya; Batty, Christopher (Association for Computing Machinery, 2022-12)Simultaneous coupling of diverse physical systems poses significant computational challenges in terms of speed, quality, and stability. Rather than treating all components with a single discretization methodology (e.g., ... -
Fast Marching-Cubes-Style Volume Evaluation for Level Set Surfaces
Takahashi, Tetsuya; Batty, Christopher (JCGT, 2022-06-30)We present an efficient and accurate volume evaluation method for grid-based level sets that computes the volume of the implicitly represented shape(s) in a manner consistent with Marching Cubes surface reconstruction. We ... -
FrictionalMonolith: A Monolithic Optimization-based Approach for Granular Flow with Contact-Aware Rigid-Body Coupling
Takahashi, Tetsuya; Batty, Christopher (Association for Computing Machinery, 2021)We propose FrictionalMonolith, a monolithic pressure-friction-contact solver for more accurately, robustly, and efficiently simulating two-way interactions of rigid bodies with continuum granular materials or inviscid ... -
Monolith: a monolithic pressure-viscosity-contact solver for strong two-way rigid-rigid rigid-fluid coupling
Takahashi, Tetsuya; Batty, Christopher (Association for Computing Machinery, 2020-11)We propose Monolith, a monolithic pressure-viscosity-contact solver for more accurately, robustly, and efficiently simulating non-trivial two-way interactions of rigid bodies with inviscid, viscous, or non-Newtonian liquids. ...
