The standard model of solar flares is explained. Then we present processes in solar flares and their simulations in magnetohydrodynamic and particle-in-cell models. Maps of waves and oscillations based on the broadband radio spectrum are added. A role of thermal fronts in solar flares is mentioned. Finally, a question of solar superflares is shortly discussed.
