Radial mass accretion rate within the inner disk for all runs (solid colored lines) as a function of cylindrical radius and computed using Eq. (21) at a moment in time when R_d has reached ≈1 AU. Only cells belonging to the inner disk were used in the computation of Ṁ_s. Panel a displays the measurements of Ṁ_s made using ⟨v_r⟩_z (Eq. (22)), whereas panel b displays the same measurements made using ⟨v_r⟩_ρ (Eq. (23)). The solid gray lines are analytical estimates of radial transport computed using Eq. (26), with α_sh = 10⁻¹ (top), 5 × 10⁻² (middle), and 10⁻² (bottom). The other parameters for the solid gray lines are M_* ≈ 7 × 10⁻³ M_⊙; R_* ≈ 3 × 10⁻² AU; c_s0 ≈ 5 km s⁻¹; β ≈ 3; ξ ≈ 3/2, and γ ≈ 1.1.
