 The distance of the recycling plane from the inflow boundary can be set with parameter [#recycling_width recycling_width]. The height above ground above which the turbulence signal is not used for recycling and the width of the layer within the magnitude of the turbulence signal is damped from 100% to 0% can be set with parameters [#inflow_damping_height inflow_damping_height] and [#inflow_damping_width inflow_damping_width].\\\\
 The detailed setup for a turbulent inflow is described in [../examples/turbinf here].

+When set true, a turbulent outflow condition is used at the outflow boundary. This outflow condition works similar to the turbulent recycling method, but instantaneous values are copied from a vertical source plane (see [#outflow_sourec_plane outflow_sourec_plane]) from inside the domain to the outflow boundary. This prevents numerical errors which can occur if negative velocity values appear at the outflow boundary while using the radiation boundary condition.\\\\
+For using this outflow method [#bc_lr bc_lr] = '' 'dirichlet/radiation' '' is required. This method can only be used for an outflow boundary at the right model boundary, so far.\\\\
+The vertical source plane from where to copy the values of u, v, w, pt, q, s, and e should be placed not too close to the outflow boundary.
