Specifies the direction vector (cosine) which defines the direction of the wind. The magnitude of the vector is not significant. For example:
-
Wind in X direction, vector is 1, 0, 0
-
Wind in Z direction, vector is 0, 0, 1
-
Wind at 45 degrees, vector is .707, 0, .707
You only need to specify the method and the wind direction if you are using a pressure or velocity versus elevation table. After clicking User Wind Profile, a dialog box prompts you for the corresponding pressure or velocity table. You only need to make a single entry in the table if a uniform pressure or velocity is to act over the entire piping system. Otherwise, type the pressure or velocity profile for the applicable wind loading.
