Foil 36 8:Non-Moving Black Holes (Centered)

From Overview of BBH Simulations Physics Colloquium -- Oct 29 1998. by Scott Klasky


Found that by "smoothing" out the outer boundary that we were able to prolong and in some cases apparently lead to stable evolutions.
Find that the "proper" imposition of coordinate effects may be required. Our exact specification seems to be leading to coordinate drifting and hence our inner boundary instability.
One set of runs where results converge to a static solution (taken to be stable. Changes go down towards roundoff).
Longest prior evolutions due to Daues(~140M).
Problems occur when the outer boundary is at a large M.
