Highlights of our 3D fiducial model. Left: surface density deviations in the disk compared to the azimuthally averaged surface density , showing azimuthal structure in the form of spirals and vortices. Middle: vertical velocity of the gas at the disk midplane; quasi-axisymmetric stripes reveal VSI activity. Right: a map of the gas vortensity deviations compared to the initial (Keplerian) vortensity ϖ₀, highlighting two vortices orbiting at R ≈ 1.15 R₀
