Comparison of all primitive variables in the interior of the Data-Driven simulation at a horizontal slice at k = 15 cells above the driven boundary (z ≈ 1.59), between the GT simulation (columns 1, 5) and simulations driven every 20 δt (columns 2, 6), 50 δt (columns 3, 7), and 100 δt (columns 4, 8). The horizontal axis is x, the vertical axis is y, and data corresponds to Courant step 320, or t = 1.18. The color scale for each primitive variable is common for all simulations. The top row compares the density in the left four columns and internal energy density in the right four columns. The next three rows compare components of the velocity field (left) in a red–blue color map and magnetic field (right) in a gray-scale color map.
