    5757The non-dimensional profiles for this run line up nicely with Bondi's Fig. 3 (curves III and IV):

     61Note -- I did this lineout from the center of the first zone in the octant surrounding the sink, to the zone center at the edge of the boundary. Aside from doing a spherical average over shells, I think this will provide the most accurate results from Visit (rather than along cell boundaries, which I am not sure how Visit interpolates..)

     63Calculating the mass flux through spherical shells surrounding the sink seems to agree well with the predicted value of $\dot{M}_{BH}=8646.9$. I tried at 3 different radii: $r=5<R_s$, $r=7>R_s$, $r=25>OBS$, where $OBS$ is the spherical boundary in the grid beyond which the Bondi solution is pasted into cells.
