The plots below compare the sphere-wind simulation at two different resolutions. The low-resolution sim had 32 cells / , while the high-resolution sim had 64 cells / . Both simulations were run on a grid with physical size pc, but the high resolution had cells, so the spatial resolution was 12.8 cells / parsec, vs 6.4 cells / parsec for the low resolution run. Both simulations use the new initial cloud density profile, which tapers exponentially to the wind density floor, starting at a cloud radius of 4.5 pc. The center of the cloud has a constant density. Both clouds have a mass of 10 solar masses.
Movies of both simulations are available: low resolution and high resolution.
