Step 8: 2D Contours

  In postprocessing a turbomachinery solution, it is often preferable to display contours on constant spanwise coordinates and then, project these contours onto a plane. This permits easier evaluation of the contours, especially for surfaces that are highly three-dimensional. ANSYS FLUENT allows you to display contours in this manner using the Turbo 2D Contours dialog box.

1.   Display 2D contours of Mach number (Figure  25.7).

Turbo $\rightarrow$ 2D Contours...

(a)   Select new-topology-1 from the Turbo Topology drop down list.

(b)   Select Velocity... and Mach Number from the Contours of drop-down lists.

(c)   Enter 0.5 for Normalised Spanwise Coordinates.

Note:   For highly curved edges, if a surface is created very close to the curved edge the resulting surface may have some void spaces in it.

(d)   Click Display.

(e)   Use the mouse to obtain the view shown in Figure  25.7.

(f)   Close the Turbo 2D Contours dialog box.
