magnitude

Synopsis

calculate the magnitude of a vector field

Input Port

in_field	Mesh + Node_Data
ui_parent	user interface parent object

Parameters

data component

UIradioBoxLabel

component to calculate magnitude

Output Port

out_fld	Mesh + Node_Data
out_obj	output renderable object

Description

magnitude calculates the magnitude of a vector field.

Input

in_field

The input is any mesh with Node_Data.

ui_parent

A port to connect to a user interface object that contains the macro's widgets. By default, it is connected to the default user interface object in the application in which the macro is instanced. (This default connection is not drawn.)

Parameters

data component

UIradioBoxLabel. Radio buttons to pick which component to use to calculate the magnitude. This component can contain one-, two-, or three-vector subcomponents. The default is the first (0th) component. If node data labels are present, they are displayed.

Output Port

out_fld

The output field is a reference to a new object that is the merge of the new Node_Data, plus a reference to the original input mesh. This new Node_Data is a scalar representing the magnitude.

out_obj

This is a renderable version of the output field.

Algorithm

The equation used to compute the magni
tude is:
where a1, a2, and so on are the individual vector subcomponents within the selected component.
