Mixed Variational Finite Elements for Implicit, General-Purpose Simulation of Deformables
Ty Trusty, Danny M. Kaufman, David I W Levin
We propose and explore a new, general-purpose method for the implicit time integration of elastica. Key to our approach is the use of a mixed variational principle. In turn its fin…
Affine Body Dynamics: Fast, Stable & Intersection-free Simulation of Stiff Materials
Lei Lan, Danny M. Kaufman, Minchen Li +2
Simulating stiff materials in applications where deformations are either not significant or can safely be ignored is a pivotal task across fields. Rigid body modeling has thus long…
Codimensional Incremental Potential Contact
Minchen Li, Danny M. Kaufman, Chenfanfu Jiang
We extend the incremental potential contact (IPC) model for contacting elastodynamics to resolve systems composed of codimensional DOFs in arbitrary combination. This enables a uni…
Hierarchical Optimization Time Integration for CFL-rate MPM Stepping
Xinlei Wang, Minchen Li, Yu Fang +5
We propose Hierarchical Optimization Time Integration (HOT) for efficient implicit time-stepping of the Material Point Method (MPM) irrespective of simulated materials and conditio…
Metamorphs: Bistable Planar Structures
Gaurav Bharaj, Danny Kaufman, Etienne Vouga +1
Extreme deformation can drastically morph a structure from one structural form into another. Programming such deformation properties into the structure is often challenging and in…
