v23 v24 48 48 == Questions / Tests == 49 49 50 === Are there any quantities that are stepped on each timestep in the kernel, or are quantities only summed/subtracted during injection/accretion steps?===50 ==== Are there any quantities that are stepped on each timestep in the kernel, or are quantities only summed/subtracted during injection/accretion steps? ==== 51 51 52 52 Thinking how does the flow change over time such that the kernel switches from infall to outflow. 53 53 54 === Is the amount of "push" in the outflow subject to resolution?===54 ==== Is the amount of "push" in the outflow subject to resolution? ==== 55 55 56 === When we remove gas from cells, do we need to apply a pressure to those cells (if not, do we see any artificial waves generated due to the sudden pressure loss in those cells?)===56 ==== When we remove gas from cells, do we need to apply a pressure to those cells (if not, do we see any artificial waves generated due to the sudden pressure loss in those cells?) ==== 57 57 58 === How is the Bondi speed used in the accretion module?===58 ==== How is the Bondi speed used in the accretion module? ==== 59 59 60 60 If we can estimate the infall speed of the material around the sink as approaching the Bondi limit (is this simply pressureless collapse?), then when does $V_{out}$ > ~ $f_a V_{bondi}$, where $f_a$ is the fraction of accreted mass to be injected in outflow. 61 61 62 === Why do we conserve the center of mass (COM) of the system -- is it the location of the sink particle (if so, doesn't that coincide with the gravitational potential minimum?)===62 ==== Why do we conserve the center of mass (COM) of the system -- is it the location of the sink particle (if so, doesn't that coincide with the gravitational potential minimum?) ==== 63 63 64 64 65 === What is the spin angular momentum of the sink and how do we calculate it? ===65 ==== What is the spin angular momentum of the sink and how do we calculate it? ==== 66 66 67 67
