functionwindDirectionModifier
Wind direction modifier that is used to compute the wind-driven convective heat transfer coefficient
Extends from Modelica.Icons.Function (Icon for functions).
Information
Function that outputs 1 if the incidence angle is below 100 degrees, and 0.5 otherwise. The implementation is once continuously differentiable in its input arguments.
See Buildings.HeatTransfer.Convection.Exterior for an example that uses this function.
