    67 Despite these agreements with theory, and the fact that the sonic point lies well beyond the accretion kernel, there is a spurious outflow being generated within the accretion kernel. Contrary to intuition, this outflow propagates beyond the accretion kernel into the grid, disrupting the upstream hydrodynamic solution.. This happens ''very'' quick in the simulation ($\sim1/30 ~t_{sc, amb}$). Here is a snapshot of density illustrating this effect:
