Hi all! I'm attempting to conduct a fluid-stucture simulation of an airfoil with a moving flap. I defined all my parameters and boundary conditions. I went back step-by-step and checked the boundary conditions and also the solid properties (such as Poissons ratio) and these haven't solved this error. What could I be doing wrong? Any advice is appreciated. Thanks!
Here's my setup: I have an airfoil in a air box
Laminar Flow (Air normal inflow velocity at 200m/s) Initial pressure: 101325Pa Noslip wall condition Outlet pressure total condition: 101325Pa
Solid Mechanics (wing is aluminum, used material defining properties)
Parametric sweep changing angle of flap on wing

To no avail, these suggestions have not helped yet.
