Iteration counts, energy-integrated number densities, temperature, electron fraction, and lepton number and energy conservation results for the nested AA solver on the relaxation problem with low collision rate ρ = 1.032 × 1012 g cm−3, T = 8.806 × 1010 K, Ye = 0.1347. The solver is applied without the presolve step and run to various maximum outer iterations (MaxIter) with time step Δt = 10−1 ms.
