Top row: average temperature (left panel) and internal energy (middle panel) of the entire x − y plane and average square current density (right panel) of the flux tube (for ρ ≥ 0.9 f(z)) per height and over time. Bottom row: temperature (left panel), internal energy (middle panel), and density (right panel) at the x − y plane at the apex (z = 0). Data depict the ColdIngr model. The period of the driver is P ≃ 171 s.
