We will view contours of temperature and species concentrations as the solution develops on a plane bisecting the mesh and passing through the axis of symmetry. To create the plane section:
- Right-click on the Derived Parts node and select .

- In the Create Section in-place dialog that appears on the left of the geometry scene, click on the Input Parts button and check that only is in the Selected list.
- In the Plane Parameters section, change the normal vector to
0,1,0.
- Select New Scalar Displayer in the Display section. The completed dialog is shown below.

- Click Create to create the plane section and add it to the geometry scene as part of a scalar displayer.
