Default How to define source in cylindrical coordinate?

Guys, I have a question. How to define a source term (in fluid zone) in a momentum equation in tangential direction for Fluent 3D?

I need to create swirl in Fluent by creating a body force/source term (in fluid zone or somewhere?) in a tangential momentum equation. But with Fluent 3D, this option is not available. Of course I desperately need to go to 3D; hence I cannot really use the option available in 2D axis-symmetric swirl in Fluent.

Please give me some suggestion to go about this problem.

Cheers
