Variation of ²⁷Al and ¹⁴N mass ratio over time for two runs where the enrichment timescale exceeds the viscous timescale. The label details the parameters of the black hole and accretion disk system. The mass, M, is expressed in M_⊙, the mass accretion rate in terms of the Eddington rate, Ṁ_Edd, and the radius in unit of the Schwarzschild radius. The two thresholds for considering different enrichment level are represented by the dash-dot and the dotted lines. While the ²⁷Al mass ratio only remain above the lines for a brief duration, the enrichment in ¹⁴N is rather stable and remains at a high level until the end of the simulation.
