Foil 44 Major Obstacles

From Overview of BBH Simulations Physics Colloquium -- Oct 29 1998. by Scott Klasky
Gauge Conditions (Coordinate Conditions).
  • Examples of Gauge Conditions
    • Maximal slicing
    • Minimal Distortion Shift
  • These equations are elliptic! (boundary conditions)
We want to construct the Lapse and shift that:
  • Minimize grid stretching; Help causal differencing
  • Not too expensive to compute
  • adapt to outer boundary
  • Questions: Hyperbolic Formalisms, other ADM formalisms, GAUGE conditions!!!!!!!!!
