    44Since revision r2259, a synthetic turbulence generation method is available in PALM. The synthetic turbulence generator (STG) follows the method proposed by [wiki:/doc/tec/bc#xie2008 Xie and Castro (2008)] with a modification by [wiki:/doc/tec/bc#kim2013 Kim et al. (2013)]. Please see the [/wiki/doc/tec/bc#SyntheticTurbulenceGenerator documentation] for a detailed description of the STG.

    6 The STG requires information about the Reynolds stresses as well as turbulent length and time scales. These can be either provided in an ASCII file (please see [/wiki/doc/tec/bc#SyntheticTurbulenceGenerator documentation]), or if not available as e.g. in case of mesoscale offline nesting these information will be parametrized (please see [/wiki/doc/tec/bc#SyntheticTurbulenceGenerator documentation]). For a detailed description of the parametrized synthetic turbulence we refer to ''< replace with doi when available > ''.

    8 All parts of the STG are modularized in module [/browser/palm/trunk/SOURCE/synthetic_turbulence_generator_mod.f90 synthetic_turbulence_generator_mod]. In this context, a new Fortran NAMELIST {{{stg_par}}} was added, containing all related steering parameters. To use the STG, simply add the {{{stg_par}}} namelist to the parameter file of the run.

    1010The STG requires [../initialization_parameters#initializing_actions initializing_actions] = 'inifor', 'set_constant_profiles', or 'read_restart_data'. In case of [../initialization_parameters#initializing_actions initializing_actions] = 'set_constant_profiles' or 'read_restart_data', non-cyclic boundary conditions along x-direction ([../initialization_parameters#bc_lr bc_lr]='dirichlet/radiation') and cyclic boundary conditions along y-direction ([../initialization_parameters#bc_ns bc_ns]='cyclic') have to be used.
