The new derived part that will be created is the one- dimensional curve along the surface of the blunt body shown in pink below.
Right-click on the Scenes node. Select New Scene > Geometry.
In the bluntBody window, right-click on the Derived Parts node and select New Part > Plane Section...
A new interactive in-place dialog will be placed next to the Graphics window to allow definition of the derived part.
To define the source part for this derived part, click on the Input Parts button to activate the Select Objects dialog.
Change the selections so that subdomain-1:Inner_Wall is the source part. Click Close in the Select Objects dialog.
Tick the Plane Tool checkbox to display a tool that allows interactive definition of the plane that will cut the blunt body. Rotate and pan the image as needed so that the inner wall is in front of the plane tool rectangle as shown.
Leave the Display group box at its default setting.
The "barbell" represents the normal of the cutting plane, which you can change by dragging one of the balls to a new location. The plane can also be dragged to change the origin of the cutting plane. A bounding box slightly larger than the regions in the scene is displayed to limit the plane's movement.
Move your mouse over the plane tool, then click-and-drag the rectangle so that it cuts the blunt body close to the symmetry plane.
Click Create.
In the bluntBody window, a new node has been added within the Derived Parts node: plane section. This is the implicit part that was created.
Click Close in the dialog. It is now possible to plot data on the new surface.
