Default UDF to change Rotation Speed in a MRF simulation

Does anybody know if it's possible define a UDF to change the rotation speed in a Moving Reference Frame unsteady simulation? If you have a variation in time of a variable (x-component of velocity for example) you can write the udf to give an u(t) law and than load it in the boundary-condition (velocity inlet) panel. For fluid, when you define the MRF there is NOT the menu to load the user-defined variable! How can I do?

Thank to all Bye

accelerating udf for MRF is available on fluentusers.com. This has been in existence for a long time now.

Thank you red lemon.If you have it, can you post here?

Another information : is possible a similar udf also for Sliding Mesh acceleration? Thank you so much.

Hi,
I need UDS that change the rotation speed in a Moving Reference Frame unsteady simulation so, have you it? i couldn't find it on fluentusers.com.

thanks a lot for your help.
