Found that we can "move" a black hole (an excised region) for 3 black hole radii. |
Importance here is that we can correctly propagate the black hole such that points that were previously excised are causally updated. |
Data show that trailing end of black hole is smoothly update. |
Problems however, with coordinate conditions. |
