8: Putting it together
Broke down the problem into a series of experiments
- Placing a different number of buffer zones in AH.
- Evolve moving black holes
- Using outer boundary conditions improve evolutions.
Longest running 3D evolution of static black hole.
Cauchy evolution of a propagating hole
- Black hole excision is indeed practical and feasible in a situation where the excised regions propagate through the computational domain
- Issue is now with maintaining coordinate conditions and less with finite difference stability at the inner boundary
