Photospheric motions are believed to be the source of coronal heating and of velocity fluctuations detected in the solar corona. A numerical model. based on the shell technique applied on reduced magnetohydrodynamics equations. is used to represent energy injection due to footpoint motions. https://www.roneverhart.com/HP-Pavilion-15-eg1053cl-15-6-FHD-Touch-Intel-Core-i5-1235U-3-30-GHz-Intel-Iris-Xe-Graphics-12-GB-DDR4-RAM-512-GB-SSD-/
