Projection of the inner disk for runs 1 to 5 (top to bottom) at t = 0, 50, 100, and 150 kyr (from left to right) measured perpendicular to the initial plane of the inner disk and azimuthally averaged column density profile at the shown snapshots (rightmost panels). The azimuthally averaged column density in the rightmost panels was computed within a vertical extent of z = ±6 AU and the darkness of the line corresponds to the time of evolution (from light orange representing t = 0 kyr to dark orange at the end of the simulation). We note that the inner part is affected by accretion onto thecentral star and gravitational softening. We therefore exclude the inner region within r = r_acc + 5 AU = r_grav,soft + 10 au = 20 AU in the azimuthally averaged column density profiles.
