General Module Function
The magnitude module calculates the magnitude of a vector field data component at every node in a mesh. Input to magnitude must contain a mesh of any type and nodal data. Nodal data components can be scalar or vector with up to 3 vector subcomponents.
Module Input Ports
Magnitude has only one input port. Input to this port must contain mesh data of any type mesh and nodal data.
Module Output Ports
Magnitude has two output ports. The first output port (closest to the left) outputs a new nodal data component consisting of a scalar data component representing the calculated magnitude at every node. Output mesh data is referenced to the input mesh data. The second port outputs a renderable geometry.
Module Control Panel
The control panel for magnitude is shown in the figure above. Data component radio button are used to select which data component is to be considered by magnitude. The default selection is the first (0th) data component. The data component selected can be a scalar or a vector with up to three vector subcomponents. Only one data component can be selected at a time. Therefore, any modules downstream of magnitude will receive only the data component selected in magnitude.
