Default Moving Reference Frame UDF

I was wondering if it was possible in FLUENT to define the fluid with a moving reference frame in an unsteady simulation using a UDF.

i.e. In: Boundary Conditions, Fluid, Motion, Motion Type, define the y-velocity using a UDF.

I have been unable to find this option in the UDF manual.

Many Thanks

You can use a udf with MRF for accelerating rotation if that's what you mean.
