Turbulence Model (2D) Data Fields (InfoWorks)

Turbulence Model (2D) objects are used to define the turbulence characteristics which can be applied to either an entire 2D Zone or to specific Turbulence Zones (2D) in a network.

Note: To view all data relating to this object, use the Object Properties Window. These data fields are read-only in ICMLive Operator Client. Network objects are configured in InfoWorks ICM Ultimate and ICMLive Configuration Manager. Please refer to the InfoWorks ICM help for more details.

The following describes all the data which can be used to define a Turbulence Model (2D).

Fields that are common to the majority of objects can be found in the Common Fields topic.
