Not supported yet

The settings for evolving turbulence. In the case of a normal turbulent wind field, the turbulence is "frozen" and approaches the turbine at a constant block. Although this doesn't match physical reality, it is a particular problem for Lidar - as it gives them a "perfect" insight into the oncoming wind field. In order to represent the nature of real turbulence, a second turbulence file is superimposed on the windfield so that it "evolves" as it moves forward. This is computationally expensive, and is usually applied only to the Lidar readings - although it can be applied to all the wind values in a simulation.

Properties

SecondTurbulenceFilepath: stringcoming soon

The filepath or URI of the second turbulence file. The turbulence in this file will be used to simulate an evolving turbulence field.

Method: string, optionalcoming soon

The method used to combine the turbulence in the two turbulence files.

ExponentialFactor: number, optionalcoming soon

The exponential factor for use in the exponential model.

ApplyTo: string, optionalcoming soon

Evolving turbulence is usually only applied to Lidar readings, but it can be applied to all wind values.
