How could I rotate the 2-D image about the origin of axes ? It's only to give the airfoil the appearence of angle of attack.

Thanks in advance.

You can use the transform command in the display/scene description menu which allow you to scale, rotate and pan your image.

Thanks for your answer, but I meant rotate a image by a exact angle, let me say, 1, 2 or 6 degrees.

Is that possible ?

If I understand your intentions correctly, you should be able to achieve what you want by using the text menu in fluent as follows:-

/display/view/camera/roll

This will allow you to enter an angle which will rotate your 2d image on screen.

Yes you can parameter your rotation angle with scene display/transform command.
