But I need to make the analyses on AOA =4.5 deg this is my problem! I'm using CFX and I've Already created the enclosure around the Wing and the mesh too. I've used expressions on CFX to define AOA and the initial velocity (actually the velocity is a constant). And I've defined Ux e Uy the velocity o axis X and Y Ux = velocityXcos(AOA) Uy =velocityXsin(AOA) but every time that I put this program to run something wrong happened. and the simulations is stopped someone have an idea? let me know it Please I need help!!!
