v305 v306 33 33 The Boussinesq approximation assumes an incompressible fluid. The density is assumed to be spatially and temporally constant. Internally the density is set to 1 kg/m3. \\\\ 34 34 '' 'anelastic' '' \\ 35 The anelastic approximation allows for a density decrease with height. The density is however still horizontally and temporally constant. The vertical profile of the density is computed based on the [#surfaces_pressure surfaces_pressure] and the vertical profile of the potential temperature. The anelastic approximation requires [#momentum_advec momentum_advec] = "ws-scheme" and [#psolver psolver] = "poisfft", "sor" or "multigrid_noopt". [#psolver psolver] = "multigrid" is currently not supported. Furthermore, [#conserve_volume_flow conserve_volume_flow] = .TRUE. is not supported.\\\\35 The anelastic approximation allows for a density decrease with height.
