Default introducing angle of attack on ICEMCFD HEXA

hello sir,

i have to simulate flow around a NACA0015 airfoil at diffirent angle of attack using CFX.

i have create a 2d extruded mesh using scripts file option(file.txt) on ICEMCFD Hexa (multiblock topology).but this is done considering angle of attack equal to zero.

My question is:

what have i to do, to introduce different angle of attack? is there any possibility to introduce the angle of attack after having the 2d extruded mesh?or have i to do this at the tetin file (geometry file)?and how?

please,i will be greatfull to recieve any idea.

Hello,

you don't have to do anything in the mesh for putting angle of attck of the flow.But while solving using CFX ,in the boundary conditions for the incoming flow put u and v component of the velocity corresponding to the required angle of attack. i.e u=Vcos(aoa) v=Vsin(aoa); V is the resultant velocity.
