No Time Variation of Wind Speed

Use this option to specify the wind conditions for a simulation when no variation of the wind field with time is required. Any steady-state spatial variations defined by wind shear, tower shadow and an upturbine wake will apply.

Click the Wind icon on the toolbar, select Time varying wind, and choose the No variation option.

Enter the following parameters:

• Wind speed: the steady wind speed to be used in the simulation.

• Height at which speed is defined: the reference height to which the wind speed applies, unless Refer to hub height has been selected. If wind shear is defined, the wind speed at any other height will be different.

• Wind direction: measured clockwise from North - see wind direction.

• Flow inclination: for non-horizontal flows (e.g. on the side of a hill). A positive value indicates a rising flow.
