Overview of BBH Simulations

Given by Scott Klasky at Physics Colloquium on Oct 29 1998. Foils prepared Jan 31 99

Physics Colloquium Oct 29 1998 based on Binary Black Hole (BBH) Computational Grand Challenge
1. Understand black holes & gravity waves
2. Learn the Einstein field equations
3. Convert eqns. To eqns. We evolve numerically
4. Model these equations on a computer
5. Modeling black holes
6. Understand the inner boundary
7. Understand the outer boundary
8. Putting it together
9. Model the elliptic pde's
10. Build computational infrastructure
To really model 2 black holes, we better understand the "real" problems!!
