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.

Silly question: isn't that something you set up in your flow solver? ICEM is just the grid generator.

In CFX pre you specify a velocity inflow direction for your simulation. Without changing your grid you can change the inflow direction of your boundary condition. It's simple.
