Creating a New Reference frame in fluent and setting it to solve the case

  Dear All., Basically am working on a project determining drag and lift coefficient of an aerfoil at different angle of attacks.
  One way to change angle is by giving x and y components on velocity at inlets.
  Other way is to rotate the coordinate frame to the desired angle, and providing velocity normal to boundary. Am able to create a refrence frame at desired angle, but dont know how/where to set this frame to solve the case. by default fluent is considering global reference frame. ( IN CFX its easy, theres an option to set user defined frame to solve case).
  Please help me to figure this out. enclosed snip of a new coordinate frame created.

  Doesn't look like it. I'd be having a very careful look at the mesh too.

  It doesn't look like you can, hence my comment.
