From Overview of BBH Simulations Physics Colloquium -- Oct 29 1998. by Scott Klasky
1 Stability of the inner boundary: Sources of problems
  • Finite difference instabilities
  • Enforcing coordinate conditions so that coordinate pathologies do not develop.
2 Current research efforts are on interpolation techniques
  • Want O(h4) interpolations to get second order results.
    • Problem is getting symmetric stencils.
