AB: A pseudospectral method is used to solve the three-dimensional, nonlinear reduced magnetohydrodynamic equations. The model is applied to auroral flux tubes and we investigate the development of fine scale structure through nonlinear wave coupling. Further refinements and applications, such as the inclusion of compressibility and the study of density cavity formation, are discussed.
