hello! I am trying to run the simulation on a symmetric airfoil for steady and unsteady case for different angle of attack. I have done the meshing and wanted to change the AoA using the parameters but as soon as I give some angle to the airfoil the face mesh gets the error. I want to resolve this issue by changing the AoA of the airfoil without disturbing the mesh and running the calculation smoothly for different AoA.
I am attaching the pic for look into it.

Have a look at the NACA tutorials and examples in Help and Learning. It's common to alter the flow direction in the solver rather than alter the geometry. If you do want to alter the geometry you may well need to alter the mesh!
