CTRANS and DTRANS
 

Hi,

I really really need some information about CTRANS and DTRANS in Fluent 12 because I can't find any in tutorials or UDF manuals.
My probleme is that i want to make a wind turbine rotate but the wind is so strong that the turbine is going backward.
So does anybody know how to allow only a X-rotation for exemple.

Thank a lot in Advance
