Radial profiles at t = 1.5 T_disk for temperature T and effective Toomre Q parameter for all simulations with the highest resolution on the finest grid, normalized in radial direction. The simulation with Q_init = 3 is added for comparison. Again, we see a different behavior of the simulation with R_disk = 100 AU and Q_init = 1, displaying a smaller increase in temperature because of its smoother transition zone. The dips where the Q parameter goes below 1 are consistent with the density peaks in Figs. 10 and 12.
