Results for the non-uniform coronal heating pulse released in MHD simulations of the sheared arcade (Sect. 4.2), run with different levels of transverse resolution. The panels show the temperature, density, pressure and velocity parallel to the magnetic field (v_b) as functions of position across the arcade, at a coronal height of x = 25 Mm, at the time of the first density peak (t = 150 s). The lines are colour coded in a way that reflects the transverse resolution used with solid blue representing the N_y = 1024 solution and dashed red (dashed green) corresponding to N_y = 256 (N_y = 64).
