2D Cross-Section Line Plots

The 2D line cross-section plot visualizes a quantity in one or several lines in time, along a parameter range, or for several eigenvalues.

Creating a 2D Cross-Section Plot Using a Cut Line data set

1	Create a Cut Line 2D data set.

-	Enter the 2D coordinates for the plot. Set the start and end point of the line under x and y, for Point 1 and Point 2.

-	Select the Additional parallel lines check box to visualize on a set of parallel lines. Enter the Distances from the line as space-separated values.

2	Add a 1D Plot Group (). In the Settings window, select Cut Line 2D as the Data set.

3	Add a Line Graph and keep From parent to use the same data set as the plot group to which it belongs. Settings under y-Axis Data and x-Axis Data determine the quantity on those axes.

4	Continue to define the Line Graph as needed.

5	Click the Plot button (), right-click the node, and select Plot, or press F8.

Creating Interactive 2D Cross-Section Line Plots

1	In the Model Builder, click a 2D Plot Group node to display the buttons available on the Plot toolbar.

2	On the Plot Group contextual toolbar, click the First Point for Cut Line button (). Click a start point on the geometry. COMSOL Multiphysics chooses default coordinates as a vertical line intersecting the data in the middle.

3	Click the Second Point for Cut Line button (). Click an end point on the geometry.

A line connecting the two points is displayed in the Graphics window. The first time the cross-section toolbar buttons are clicked, a Cut Line 2D data set and a 1D Plot Group with a Line Graph are added to the Model Builder.

4	Adjust the cut line as needed by clicking the buttons, then click the geometry to change where the first and second point start and end (respectively). The coordinates are updated automatically in the data set and plot group. Click the 1D Plot Group node to view the updates to the line graph.

5	Continue adjusting the cut line until the line graph representing the points plots the data as needed.
