 In 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 e, to which a Neumann (zero gradient) condition is applied. At the outflow, a radiation condition is used for all velocity components and the calculation method of the required phase velocity is controlled by the parameter [#use_cmax use_cmax].
 For scalars, a Neumann condition is used. For the perturbation pressure, Neumann conditions are assumed both at the inflow and at the outflow.\\\\
-In 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].\\\\

 In case of non-cyclic horizontal boundaries [#call_psolver_at_all_substeps call_psolver_at_all_substeps] = ''.T.'' should be used.\\\\
