I am currently working on a project where I am going to do a static analysis of a rib structure using pressure load data obtained from a CFD simulation of the wing in ANSYS Fluent.
However, I have encountered an issue during the analysis. The pressure values on the rib remain unchanged compared to those on the wing. It seems like the program didn't account that the surface area reduced along the Z-axis. I anticipated that the pressure on the rib should proportionally increase due to the reduced surface area.
I'm wondering if ANSYS Fluent has a specific feature or method to handle this kind of analysis and help me achieve the desired results. I'd greatly appreciate any guidance, advice, or insights on how to properly set up and execute this type of static analysis within ANSYS Fluent.
Thank you in advance for your assistance!

If you post some images of the Fluent results we may be able to spot something.

Have you done a mesh sensitivity study? Have you checked the model, materials, and convergence? If so that may be the correct answer. What does theory/experience tell you?

Everything seems to be good. I checked the mesh by comparing cl results for different angles of attack with real empirical research conducted on the Selig 1223 airfoil profile

I'm wondering if it's possible to modify the results of a CFD simulation to make the imported pressure load increase proportionally as the surface area decreases

You mean scale the force? I'm not sure what you can read in Mechanical, but you could export xy data (pressure with x or y position) from Fluent and mess with that.
