Three-dimensional overview of the simulation domain above the photosphere at t = 4414 s. The colored line structures represent the magnetic field lines in the simulation area, with colors corresponding to the field strengths. The grayscale slice at the bottom illustrates the distribution of the longitudinal magnetic field at the solar surface. Yellow and red isosurfaces represent the regions where temperatures are above 20 000 K. The purple box represents the region of interest. More details can be found in the supplementary online.
