Averaged profile of the local kinetic energy normalized with respect to the kinetic energy in the midplane for the 25, 50, 101, and 203 cells per H_R at R₀ = 1 AU. Thevertical colored lines represent H_R = 6.2, where the X-ray–FUV heated boundary layer is (in dark green), and the H_R = 9.7, where the EUV heated region is located (in purple) (same as in Fig. 2). The models for 101 and 203 cells per H_R are in good agreement. The density floor is located H_R = 13, and therefore does not influence our result.
