Hi all,
I'm relatively new to CFX and I have a question regarding obtaining data from results. I sketched an airfoil in geometry, applied the meshing and setup and ran the solution. I now have results as per the image below. What I would like to do next is pull velocity and pressure data from various points along the airfoil. What's the best way to do this (add contours)? Thanks. |

Define your points on the airfoil. This can be done many ways. Then go file/export and get a CSV file, or use the points in the calculation spreadsheet tab, or use the points in CEL expressions. CFD-Post is quite flexible and can process the data in many ways.

If you want to extract pressure along the air foil, I would suggest to create a polyline as a boundary intersection. There select, the airfoil and the plane that you currently use to plot velocity.
If you have done that, you will obtain a line that you can use to plot pressure. Velocity will be zero, since you're on the wall. (with Hybrid values) |
