Fast viscoelastic behavior with thin features
Chris Wojtan,Greg Turk +1 more
TL;DR: In this article, a high resolution surface mesh with a tetrahedral finite element simulator is combined for fast and detailed simulations of complex elastic and plastic behavior, which significantly expands the range of physical parameters that can be simulated with a single technique, and the results are free from common artifacts such as volume loss, smoothing, popping and the absence of thin features like strands and sheets.
Proceedings ArticleDOI
A finite element method for animating large viscoplastic flow
TL;DR: An extension to Lagrangian finite element methods to allow for large plastic deformations of solid materials and an enhanced plasticity model that preserves volume and includes creep and work hardening/softening are presented.
Journal ArticleDOI
Highly adaptive liquid simulations on tetrahedral meshes
TL;DR: A new method for efficiently simulating liquid with extreme amounts of spatial adaptivity by leveraging an alternative Eulerian tetrahedral mesh discretization to significantly reduce the complexity of the pressure solve while increasing the robustness with respect to element quality and removing the possibility of locking.
Journal ArticleDOI
Deforming meshes that split and merge
TL;DR: In this article, the Lagrangian surface tracking method is used to detect and treat topological events with an emphasis on the preservation of detailed features, while simultaneously simplifying those portions of the material that are not visible.
Journal ArticleDOI
A multiscale approach to mesh-based surface tension flows
TL;DR: In this paper, the authors present an approach to simulate flows driven by surface tension based on triangle meshes, which consists of two simulation layers: the first layer is an Eulerian method for simulating surface tension forces that is free from typical strict time step constraints.
