CST2013: 2D Vector Plot

2D/3D Plot: Properties

You can use 2D vector plots to display 2-dimensional fields as arrows. You may also display 2D cuts from 3D fields by choosing the option 2D/3D Plot: 3D fields on 2D plane or the corresponding item from the context menu.

Phase/Animation (Time/Animation) frame

Phase / Time: Specify the phase in degrees for frequency monitors or time in your unit in case of time monitors.

Start / Stop: Click here to start / stop the animation.

Settings…: Opens a dialog box where you can specify field animation settings like step width.

Arrows frame

Sparse/dense slider: Specifies the number of arrows used for the plot.

Color by value: Colors the arrows depending on their value. See the Color Ramp dialog box to modify the color mapping. This feature is only available in the engine mode "legacy".

Scaling frame

Min/Max slider: The slider defines a factor that will be multiplied to the field strength, thus you can influence the maximum arrow size.

log: Turns on logarithmic scaling.

Strength: You can vary the characteristic curve used for logarithmic scaling. Values from 1.0e-6 to 100000 are allowed. A high strength value will give all arrows nearly the same size, while a strength close to 0 will result in a nearly linear plot.

Logarithmic scaling will not change the maximum arrow size selected by the slider.

Cutplane control and location frame

This frame is only active if you plot a 2D plane that is cut from a 3D field. You can do this by checking the option 2D/3D Plot: 3D fields on 2D plane or the corresponding item from the context menu.

The options in this frame are the same as in the Cutting Plane dialog.

Close

Closes this dialog box without performing any further action.

Apply

Applies any changes to the visualization. Only active if changes have been made.

Specials...

Opens a dialog box to change the scaling of the arrows.

Color ramp...

Opens a dialog box offering the possibility to change the coloring of the field plots.
