Reply To: How to change airfoil angle of attack without redrawing and remeshing?

You can use dynamic mesh for that. Save case file first. Then Enable Dynamic Mesh (after you switch to transient), Under your cell zone add mesh motion and provide Rotational Speed and direction of rotation, In dynamic mesh panel run single time step a 1 second to rotate the mesh by previewing mesh motion. Save new case after you switch off dynamic mesh and transient. Other idea is to create Fluent Expressions where you incorporate the AoA in your velocity profile prescription!
