Wind decline angle (Heat Stress Overlay)

Icon	Attribute	Unit	Range	Description	Default value
	WIND_DECLINE_ANGLE	Degrees		This angle determines how the wind flows down around objects.	90

Notes

• By default the DPRA Heat stress report does not take this effect into account and the value is set to 90 degrees (making it inactive).
• However a value of e.g. 45 degrees produces more realistic wind flow around objects.
