How Much Accuracy Can FLOWUnsteady Predict for Cambered Airfoils?

[prem-tekkr]

Hello,

I’m using FLOWUnsteady to simulate a wing with both NACA0012 (symmetric) and some cambered airfoils. While I’m seeing a 5-10% error compared to CFD results for the symmetric airfoil, the error jumps to 80-90% for the cambered airfoils.

Has anyone encountered similar issues, or conducted comparisons that could provide insights into FLOWUnsteady’s predictive accuracy for wings with both cambered and symmetric airfoils?

Any advice or potential solutions would be appreciated!
