# On the role of initial and boundary conditions in numerical simulations of accretion flows

@article{Bu2013OnTR, title={On the role of initial and boundary conditions in numerical simulations of accretion flows}, author={De-Fu Bu and Fenge Yuan and Maochun Wu and Jorge Cuadra}, journal={Monthly Notices of the Royal Astronomical Society}, year={2013}, volume={434}, pages={1692-1701} }

We study the effects of initial and boundary conditions, taking two-dimensional hydrodynamical numerical simulations of hot accretion flow as an example. The initial conditions considered include a rotating torus, a solution expanded from the one-dimensional global solution of hot accretion flows, injected gas with various angular momentum distributions, and the gas from a large-scale numerical simulation. Special attention is paid to the radial profiles of the mass accretion rate and density…
