I m wondering how to get the Gradients for the Velocity in Stn Frame..

For example:

Velocity in Stn Frame u.Gradient X

I never had a problem getting the gradiensts for a stationary domain but since we are using a rotating domain i cant find them in Post. I also tried creating a new Variable by setting Velocity in Stn Frame u.Gradient X for the expression. But the system told me that Velocity in Stn Frame u.Gradient X does not exist. By the way i m using ansys cfx 11

I would realy appreciate some help since a large part od my diplomathesis depends on this values.

regards Sebastian
