v14 v15 41 41 === Summary === 42 42 43 Authors ran simulations with an outer density of 1/1000 the density at the outermost edge of the clump, whereas my simulations used 1/100. The ambient therefore had a large sound speed throughout the constant pressure medium (pressure = pressure in sphere at edge), and since the ambient region was very large, the pressure remained nearly constant throughout. They found that if the sphere was initialized with the Larson-Penston solution, it followed the analytical LP soln'. If the grid was initialized by a singular isothermal sphere, it followed Shu'ssolution.43 Authors ran simulations of a Bonner Ebert sphere with an outer density of 1/1000 the density at the outermost edge of the clump (my simulations used 1/100). The ambient therefore had a large sound speed throughout the constant pressure medium (pressure = pressure in sphere at edge), and since the ambient region was very large, the pressure remained nearly constant throughout. They found that if the sphere was initialized with the Larson-Penston solution (uniform density sphere?), it followed the analytical LP time dependent flow. If the grid was initialized by a singular isothermal sphere, it followed Shu's self similar solution. 44 44 45 45 === Stability Tests ===
