!!!

Edit the Surface, set the color mode to variable, and the Variable to Pressure. Is this what you're after?

No. I want to get 2D graph. On X-axis I want chord of airfoil, on Y-axis I want pressure

Hi Dak,

This is the method I use:

1. Create a Plane (must be a slice) which cuts through the aerofoil at the section of interest.

2. Create a user surface which is a boundary interface between the surface and your new plane.

3. Export the data on the user surface for all the properties you are interested in.

Note: This doesn't create a line across the surface, instead it is a plane which is one element wide.

Regards

Paul

Hi,

Instead of creating a User Surface, you may create a Polyline as the intersection of the airfoil surface and the Plane you've created.

In CFX-Post, you may create a Chart, Location: Polyline ; X axis: X, Y or Z ; Y axis: Pressure

To obtain the chord, you'll have to export the geometry data and work it out.
