Kinetic energy density of the flow, Ek = 10⁻⁸, in response to the (m = 0, ω = 0.67) libration forcing in a nonstratified core with r _ICB = 0.4 and N ₀ = 0 (left column) and a stratified core with r _ICB = 0.4, r _C = 0.7, h = 0.1, and N ₀ = 100 (right column). The top row displays meridional cuts (ϕ = 0) of the kinetic energy density, while the bottom row shows the total kinetic energy density as a function of the radial coordinate.
