     132Near-surface adjustment of the mixing length to the Prandtl-layer law.\\\\
     133Usually the mixing length in LES models l,,LES,, depends (as in PALM) on the grid size and is possibly restricted further in case of stable stratification and near the lower wall (see parameter [#wall_adjustment]). With '''adjust_mixing_length''' = ''.T.'' the Prandtl' mixing length l,,PR,, = kappa * z/phi is calculated and the mixing length actually used in the model is set l = MIN (l,,LES,, , l,,PR,,). This usually gives a decrease of the mixing length at the bottom boundary and considers the fact that eddy sizes decrease in the vicinity of the wall.\\\\
     134'''Warning:''' So far, there is no good experience with '''adjust_mixing_length''' = ''.T.''{{{!}}}\\\\
     135With '''adjust_mixing_length''' = ''.T.'' and the Prandtl-layer being switched on (see [#prandtl_layer prandtl_layer]) '' '(u*){{{**}}} 2+neumann' '' should always be set as the lower boundary condition for the TKE (see [#bc_e_b bc_e_b]), otherwise the near-surface value of the TKE is not in agreement with the Prandtl-layer law (Prandtl-layer law and Prandtl-Kolmogorov-Ansatz should provide the same value for K,,m,,). A warning is given, if this is not the case.

     163Boundary condition along x (for all quantities).\\\\
     164By default, a cyclic boundary condition is used along x.\\\\
     165'''bc_lr''' may also be assigned the values '' 'dirichlet/radiation' '' (inflow from left, outflow to the right) or '' 'radiation/dirichlet' '' (inflow from right, outflow to the left). This requires the multi-grid method to be used for solving the Poisson equation for perturbation pressure (see [../d3par#psolver psolver]) and it also requires cyclic boundary conditions along y (see [#bc_ns bc_ns]).\\\\
     166In case of these non-cyclic lateral boundaries, a Dirichlet condition is used at the inflow for all quantities (initial vertical profiles - see [#initializing_actions initializing_actions] - are fixed during the run) except u, to which a Neumann (zero gradient) condition is applied. At the outflow, a radiation condition is used for all velocity components, while a Neumann (zero gradient) condition is used for the scalars. For perturbation pressure Neumann (zero gradient) conditions are assumed both at the inflow and at the outflow.\\\\
     167When using non-cyclic lateral boundaries, a filter is applied to the velocity field in the vicinity of the outflow in order to suppress any reflections of outgoing disturbances (see [#km_damp_max km_damp_max] and [#outflow_damping_width outflow_damping_width]).\\\\
     168In order to maintain a turbulent state of the flow, it may be neccessary to continuously impose perturbations on the horizontal velocity field in the vicinity of the inflow throughout the whole run. This can be switched on using [../d3par#create_disturbances create_disturbances]. The horizontal range to which these perturbations are applied is controlled by the parameters [#inflow_disturbance_begin inflow_disturbance_begin] and [#inflow_disturbance_end inflow_disturbance_end]. The vertical range and the perturbation amplitude are given by [../d3par#disturbance_level_b disturbance_level_b], [../d3par#disturbance_level_t disturbance_level_t], and [../d3par#disturbance_amplitude disturbance_amplitude]. The time interval at which perturbations are to be imposed is set by [../d3par#dt_disturb dt_disturb].\\\\
     169In case of non-cyclic horizontal boundaries [../d3par#call_psolver_at_all_substeps call_psolver_at_all_substeps] = ''.T.'' should be used.
     170
     171'''Note:'''
     172Using non-cyclic lateral boundaries requires very sensitive adjustments of the inflow (vertical profiles) and the bottom boundary conditions, e.g. a surface heating should not be applied near the inflow boundary because this may significantly disturb the inflow. Please check the model results very carefully.
