‘ZONAL LES MODEL’ object.

Attributes

Attribute	Summary
enabled	Enable the ZONAL LES MODEL object.
option	The ‘Zonal Les Model’ option.
zone_marker	Real function to mark the forcing region: values > 0.5 mean forcing On, otherwise - Off.
start_timestep_number	‘Start Timestep Number’ parameter.
smagorinsky_model_constant	‘Smagorinsky Model Constant’ parameter.
hfg_length_scale_factor	Parameter of the harmonic flow generator of the turbulence forcing model.
hfg_time_scale_factor	Parameter of the harmonic flow generator of the turbulence forcing model.
eddy_viscosity_ratio_limit	Used by turbulent dispersion model for particle tracking and by turbulence forcing model. Specify (Turb / Molecular) viscosity ratio limit, below which no turbulent tracking is performed, or no forcing of resolved turbulence is performed.

Included in:
