I am trying to simulate a front wing design. I put the underside area as my reference area. However i am getting wayyy off values of Cl and Cd. (Cl of -240 and Cd of 23) for my first wing flap.
Here is my project can you please have a look and let me know where am i going wrong.? also, is there a problem with my meshing in general? SimScale Login
Hello, make sure to have a look at this article for common issues with drag and lift coefficients: Why Are My Lift And Drag Coefficients Too Big/Small? | SimScale
Cheers
Thank you but this article doesn’t really help me solve my problem. Could you have a look at my particular simulation and then suggest suitable answers for both lift and drag coefficients as well as mesh refinement. Also for a front wing, should underside area be used or frontal area?
Figure 1 in the linked article contains the reason why your Cd and Cl values look odd.
The reference area for a front wing is typically based on a frontal view.
Cheers
