 Switch to steer the call of the pressure solver.\\\\
-In order to speed-up performance, the Poisson equation for perturbation pressure (see [#psolver psolver]) can be called only at the last substep of multistep Runge-Kutta timestep schemes (see [#timestep_scheme timestep_scheme]) by setting '''call_psolver_at_all_substeps''' = ''.F.''. In many cases, this sufficiently reduces the divergence of the velocity field. Nevertheless, small-scale ripples (2-delta-x) may occur. In this case and in case of non-cyclic lateral boundary conditions, the default value '''call_psolver_at_all_timesteps''' = ''.T.'' should be used.

       Compared to the direct method and the multi-grid method, this scheme needs substantially more computing time. It should only be used for test runs, e.g. to compare results with the other pressure solver methods.\\\\

 When 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]).\\\\
 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].\\\\

 '''Note:'''\\
 Using 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.
