33.19.2 Profile Options Dialog Box

The Profile Options dialog box controls the scaling and projection direction of profiles. It is opened from the Contours dialog box, and you will display the profiles using the Display button in that dialog box. See Section  29.1.2 for details about the items below.

Controls

Reference Value   sets the "zero height'' reference value for the profile. Any point on the profile with a value equal to the Reference Value will be plotted exactly on the defining surface. Values greater than the Reference Value will be projected ahead of the surface (in the direction of Projection Dir. and scaled by Scale Factor), and values less than the Reference Value will be projected behind the surface.

Scale Factor   sets the length scale factor for projection. After subtracting off the Reference Value, ANSYS FLUENT multiplies the resulting solution value by the Scale Factor to form a length.

Projection Dir.   sets the direction in which profiles are projected. In 2D, for example, a contour plot of pressure on the entire domain can be projected in the $z$ direction to form a carpet plot, or a contour plot of $x$ velocity on a sequence of $x$-coordinate slice lines can be projected in the $x$ direction to form a series of velocity profiles.
