Temperature evolution of the six simulations. From left to right, columns correspond to simulations with σ ∈ {0, 0.75, 1, 1.25, 1.5, 2}. Top row: Snapshots of the simulations at the time at which footpoint driving motion is disabled t = t₁. Middle row: Formation of coronal rain (σ = 0), solar prominences (σ = 0 and 0.75), and plasmoids (σ ∈ {1, 1.25, 1.5, 2}). Bottom row: Final snapshot of each simulation. Thin black lines indicate magnetic field lines. The final snapshot occurs at different timestamps for the different σ cases: 253 min (σ ∈ {0, 0.75, 1}),  257 min (σ = 1.25), 234 min (σ = 1.5), and 232 min (σ = 2).
