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.
