The Stiffness Issue

• Real-world fabrics resist strongly to stretching, once they stretch beyond certain limits.

• But, increasing the stiffness can cause problems.

  • Explicit integrators will be unstable
    • Solution: smaller time steps and more computational time.
  • The linear systems involved in Implicit integrators will be ill-conditioned.
    • Solution: more iterations and computational time.

• Can we achieve high stiffness, with a low computational cost?
