Model S1. Left column: differential emission measure versus temperature for the whole domain. Middle column: average n²-weighted velocity dispersions Δv_nt(T) (calculated as ) for the footpoint location for x-component (red solid lines) and z-component (blue dot-dashed lines) of the velocity. Right column: green dashed line is Δv_nt(T) for the whole domain; red solid lines is the Δv_nt(T) for the coronal part of the loop; black lines are Δv_nt(T) for the loop-top region (dot-dashed line is for y-component and dotted line is for z-component of the velocity). Corresponding times are shown in the left panels. Locations of the sampling regions are shown in Fig. 2.
