Left: relative wave energy flux parallel to the magnetic field averaged over time as a function of height for the localized driver. The solid green line shows the energy flux along the pore axis, whereas the dashed purple line shows the average flux across the pore up to the field line highlighted in Fig. 7. The observational data (black line with symbols) are from pore 3 of GM21. All fluxes are normalized to the first observational data point. Right: comparison of flux damping in the simulation with localized driver with the effects of geometric damping. The solid green line shows the same data as in the left plot for comparison. The other lines are explained in the text.
