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. |
