I’m a student participating in the development class of the F1 in schools competition and I was trying to create an excel file where I could easily work with values to see what works best with my car. There was one value that I couldn’t work out which was the Lift coefficient for my front and rear wing, so I decided to use SimScale to see what I could find.
The file is an incompressible fluid flow simulation over my front and rear wings I designed. I used the force coefficient plots but I don’t know how to interpret them so could someone help me with this. I have used SimScale before but i’m still quite new to the CFD concepts but I will try my best to understand so don’t hold back when explaining If you can could you also check the boundary conditions and mesh settings to see if the problem isn’t the simulation but what i’ve prepared.
I took a look at your project. Everything looks good except the result control faces that you have selected. You can refer to this portion of the aerodynamics tutorial to learn more about what faces you usually have to select.
But in short, you need to select the faces of your subject, i.e. the wing faces in your case, for the calculation of lift and drag. You have selected the wall faces of the flow region, which would give you very different results from what you would expect.
You can refer to this article to learn more about how the area or face selection would affect the lift and drag values that are displayed in post processing.
If you can could you also check the boundary conditions and mesh settings to see if the problem isn’t the simulation but what i’ve prepared.
