Snapshots of the density distribution during the evolution of the Keplerian disk. Shown are runs with deviation well-balancing and without well-balancing using explicit time stepping and resolutions of 20 × 70 cells as well as 100 × 350 grid cells. The bottom two rows show the same setup evolved with implicit time stepping at a resolution of 20 × 70 cells. To emphasize the deviation from the initial background density of 𝜚₀ = 1 we show here 𝜚 − 1 and give the maximum and minimum of this quantity in an inset for each snapshot.
