Stable Cutting of Deformable Objects in Virtual Environments Using XFEM

Stable Cutting of Deformable Objects in Virtual Environments Using XFEM

Most deformable object simulators suffer from stability problems caused by material slivers in the cut vicinity. The extended finite element method (XFEM) is a novel approach that uses element enrichment to effectively model discontinuities. In combination with an appropriate mass-lumping technique,...

Zusammenfassung:Most deformable object simulators suffer from stability problems caused by material slivers in the cut vicinity. The extended finite element method (XFEM) is a novel approach that uses element enrichment to effectively model discontinuities. In combination with an appropriate mass-lumping technique, XFEM provides a stable simulation regardless of cut location.
