55 | | Note, the sonic radius is not resolved by ~ factor of 20 in this simulation, as seen when checking dx quoted above. In this sim, the Bondi solution was initialized everywhere in the grid at t=0 (except within a small inner radius, described below). In subsequent timesteps, the Bondi solution is re-pasted into the ghost zones and a small inner spherical region at the origin. A sink particle is initialized at the origin with mass given above ($M_{sink}=M_*$). The particle can accrete gas following the Krumholz prescription. The only source of gravity in the sims is the point gravity object associated with the particle (self-gravity is turned off). |
