 Parameter to switch on usage of cloud droplets.\\\\
-Cloud droplets require to use particles (i.e. the NAMELIST group [../parpar] has to be included in the parameter file). Then each particle is a representative for a certain number of droplets. The droplet features (number of droplets, initial radius, etc.) can be steered with the respective particle parameters (see e.g. [../parpar#radius radius]). The real number of initial droplets in a grid cell is equal to the initial number of droplets (defined by the particle source parameters [../parpar#pst pst], [../parpar#psl psl], [../parpar#psr psr], [../parpar#pss pss], [../parpar#psn psn], [../parpar#psb psb], [../parpar#pdx pdx], [../parpar#pdy pdy] and [../parpar#pdz pdz]) times the [../parpar#initial_weighting_factor initial_weighting_factor].\\\\

 In case of using cloud droplets, the default condensation scheme in PALM cannot be used, i.e. [#cloud_physics cloud_physics] must be set ''.F.''.

+Convergence factor to be used with the the SOR-scheme.\\\\
+If the SOR-scheme is selected ([#psolver psolver] = '' 'sor' ''), this parameter determines the value of the convergence factor, where ''1.0'' <= '''omega_sor''' < ''2.0.'' The optimum value of '''omega_sor''' depends on the number of grid points along the different directions in space. For non-equidistant grids it can only be determined by appropriate test runs.

+Width of the damping range in the vicinity of the outflow (gridpoints).\\\\
+When using non-cyclic lateral boundaries (see [#bc_lr bc_lr] or [#bc_ns bc_ns]), a smoothing has to be applied to the velocity field in the vicinity of the outflow in order to suppress any reflections of outgoing disturbances. This parameter controlls the horizontal range to which the smoothing is applied. The range is given in gridpoints counted from the respective outflow boundary. For further details about the smoothing see parameter [#km_damp_max km_damp_max], which defines the magnitude of the damping.
