Lee wave solver This is a 2D linear lee wave solver, which can be used to find the steady wave field generated by flow over topography in the ocean or atmosphere. The context and theory behind this solver is described in *Surface reflection of bottom generated oceanic lee waves, Baker & Mashayek (2021), Journal of Fluid Mechanics, https://doi.org/10.1017/jfm.2021.627 The solution and energy diagnostics can be found, with input options including: A given topography h(x), with several defaults available. A given background flow speed U(z), varying with height above bottom. A given background stratification N(z), varying with height above bottom. A freely radiating or rigid lid surface boundary condition. The effect of rotation, using the Coriolis parameter f. The hydrostatic approximation/ nonhydrostatic flow See the README for more info
