+# Askervein Hill
+
+This is an example input file for a neutral atmospheric boundary layer (ABL)
+based on the simulation setup described in Wagenbrenner et al. 2019,
+Atmosphere.
+
+The modeled domain is a 6 km by 6 km square, centered on the hill.
+The grid has Δx = Δy = 20 m in the horizontal and an initial vertical spacing
+of Δz = 20 m in the vertical direction with grid stretching ratio of 1.08.
+Boundaries are Dirichlet inflow on the west and south, with specified power-law
+profile from literature, and Neumann outflow on the north and east; the bottom
+boundary is a surface layer based on MOST and the top boundary is a slip wall.
+
+Using the anelastic path with FFT hybrid poisson solver, we perform an unsteady
+RANS simulation with a one-equation TKE closure (see Axell & Liungman 2001,
+Environ. Fluid Mech.) neglecting Coriolis forces. Damping is provided at the
+inlets and top boundary (sponge zone and Rayleigh layer, respectively) to
+prevent terrain-induced wave reflections.
+
+The solver executable is compiled in Exec/ABL.
