We present a method for accurately tracking the moving surface of deformable materials in a manner that gracefully handles topological changes.We employ a Lagrangian surface tracking method, and we use a triangle mesh for our surface representation so that fine features can be retained. We make topological changes to the mesh by first identifying merging or splitting events at a particular grid re
An Edge-Based Computationally-Efficient Formulation of Saint Venant-Kirchhoff Tetrahedral Finite Elements RYO KIKUUWE, HIROAKI TABUCHI, and MOTOJI YAMAMOTO Kyushu University This paper describes a computationally-efficient formulation and an algorithm for tetrahedral finite-element simulation of elastic objects subject to Saint Venant-Kirchhoff (StVK) material law. The number of floating point operati
