hello, i am new to aerodynamics. I am interested on how to calculate the minimum number of inner structure of a wing must have to tolerate the maximum downforce (not deform).
Maybe my explanation not clear, here is my project:SimScale
my question is how to calculate the distance between the inner structure and how many i need to put it inside the foil.
Thank you very much.
Hi @bning12!
Interesting question you have there! Let me tag all the @power_users here who might help you out with that one! @cjquijano, have you done such a simulation before?
This is going to be a parameter study in any case as there is no rule to immediately give you the perfect design. You have to create different models and test them - there is no way around I would say. On top of that you have to make sure to create a smooth, producible and aerodynamically suitable design.
All the best!

thank you very much for giving me suggestion. moreover, i want to ask a question, how can i make all the components be a whole object? this is because i observe that the inner structure no deforming? but only the surface deform?
Hi @bning12 and no worries!
I am thinking about adding a bonded contact between the inner and outer structure as this is still missing. On top of that are you trying to simulate lift or the dead-load of the airfoil? Because if it is lift the force has to point into the other direction.
Best,
Jousef
thank you so much for your precious reply, actually i design as a formula car wing, the foil experience the downforce, and i am thinking how to calculate the number of inner structure i need to put
thank for you reply again
My bad @bning12 
Looked like an airfoil at first glance!
If you are struggling with the simulation please let us know if we can help you with anything.
All the best!
