Velocity and wall shear stress data will be plotted on parts created by intersecting a plane with the bottom wall and symmetry plane boundary surfaces, resulting in the two line segments shown below.

The wall shear stress will be monitored along the line where the BottomWall and Symplane boundaries intersect. To create a section for this:
A new node named plane section will appear.
The section is offset very slightly from the symmetry plane to ensure that realistic wall shear stress values are displayed.
The velocity will be monitored along a line segment on the symmetry plane, located at x = 0.38 m. To create a section for this segment:
A new node named plane section will appear.
These two sections will be used to create plots in the next step, Plotting Simulation Data.
