Table 1

Designation code of each simulation (Col. 1), number of cells for each coordinate (Cols. 2–4); approximate number of cells in the region r < 1500 au, i.e., the approximate number of cells that resolve the physics of the disk (Col. 5); cell size at r = 30 au (Col. 6), cell size at r = 1500 au (Col. 7).

run	n_r	n_θ	n_ϕ	n_disk	Δx₃₀	Δx₁₅₀₀
x1	34	11	32	7.0 × 10³	6.36	359
x2	67	21	64	5.3 × 10⁴	3.07	167
x4	134	41	128	4.2 × 10⁵	1.50	77.8
x8	268	81	256	3.3 × 10⁶	0.74	37.5
x16	536	161	512	2.6 × 10⁷	0.368	18.4

Notes. Δx₃₀ is also the minimum cell size of the computational domain in the midplane of the disk, and Δx₁₅₀₀ represents roughly the cell size in the outer region of the disk.
