    4739At an effective resolution of ~$dx = .0019$, the sphere is very close to HSE within .1 of its radius.
     40
     41HSE here is defined as the difference of the magnitude of the gravitational and pressure acceleration:
     42
     43$HSE =   mag[\nabla \phi_g] - mag[ \frac{\nabla P}{\rho} ]$
     44
     45==== Radial profiles over time: ====
     46
     47The following radial profile movies show the sphere is quasi-stable over 2 dynamical times, entering a breathing mode as it slowly adjusts to its HSE initialization:

     50|| pressure (Ba) || movie ||
     51|| radial mach number  || movie ||

     54==== Mesh ====

     56The mesh/setup at the final time looks like:
