How to rotate a geometry in gambit
 

I want to simulate a cavitating flow around a naca 0015 hydrofoil at an angle of 6 degree.I can make the angle by changing the x/y component of the velocity.but i would like to rotate the whole hydrofoil by 6 degree.can anyone suggest me the commands that will rotate the geometry without changing the allignment of the mesh.Thanks in advance.

You can create the mesh and then rotate the whole volume using the (with mesh) option.
or you can do it in Fluent itself
