Hi! I hope you are all doing great!

I'm working on a project in which I have to study The FSI (Fluid-Solid interaction) Between air and an aircraft wing. The interaction occurs specifically between air and the skin of the wing, I'm attaching a picture of said skin (it has been meshed already):

Hey You could also use Shell/3D surface elements (Like Shell181, Shell281) with mid-surface extraction in SpaceClaim (Refer toMidsurface tutorial (spaceclaim.com)).
But, keep in mind you cannot generate a Midsurface unless the faces have a constant wall thickness. In SC, the Midsurface tool will not select the non-parallel faces.
Nodes on Shell elements have 6 Dof's. Hence MPC based bonded contact should be used to connect shell and solid elements.
Refer to this video for more info on understanding shell elements.
