Results for the non-uniform coronal heating pulse using a two-dimensional MHD simulation of the unsheared arcade (Sect. 4.1). Starting from the left, the columns show time ordered snapshots of the temperature (T), density (n) and field-aligned velocity (v_x) for times during the heating, evaporation and decay phases. The contours are drawn according to the scales shown in the colour tables. The black curves indicate the top of the TRAC region at each of the footpoints of the unsheared arcade. Movies of the full time evolution of the T, n and v_x contour plots can be viewed online.
