Enclosed envelope mass as a function of time. Orange lines corresponds to run RADL27k0.01LONG, blue lines to RADL0k0.01LONG. Short-dashed, dashed, and solid curves correspond to the mass within a radius of respectively 0.3,0.6, and 0.9 r_H. Convergence is reached within approximately 10 orbits. The inner envelope shells take the longest time to settle, especially when the pressure balance is driven by compressional heating. The potential is introduced during one orbital period (Eq. (A.3)).
