v36 v37 59 59 [[Image(Bondi_Comparison_gamma1pt4.png, 35%)]] 60 60 61 Note -- 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..)61 (Note -- 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, as I was getting somewhat wonky results sampling along cell boundaries -- probably due to Visit's interpolatation method) 62 62 63 63 Calculating 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: $r=5<R_s$, $r=8>R_s$, $r=25>OBS$, where $OBS$ is the spherical boundary in the grid beyond which the Bondi solution is pasted into cells:
