Aeroelastic simulation discussion

I simulated the front wing of a car and needed the pressure distribution over the wing to perform structural simulation and see the performance drop or gain due to the deflection. Any idea how I can export just the pressure field over the wing surface and import it for the structural analysis.

Hey @The_Dogfather ,

That’s an interesting project. That is what we call a one-way FSI. The following article shows you exactly how you can do that:

Essentially, you export the results into ParaView (free) or any other post processing software of your choice and then extract a CSV of pressure values that you can then use as boundary conditions for your structural simulation.

Best,

Thanks a lot sir. I will try this way.

I have one more question. Is there a way to then import the deflected geometry after the structural analysis into aerodynamic analysis again to compare the change in Cl and Cd of the wing?

Hey @The_Dogfather ,

That would be a 2-way FSI, which our platform does not currently support. You can however, use the structural analysis results (modify your CAD as per the deformation values and reimport modified CAD into SimScale) to run a flow simulation on it to determine Cl, Cd, etc.
