Hi,

I simulated an axial turbine, This turbine includes two stationary frame and one rotating frame as follows:



Rotation frame=blade

stationary frame=before and after blade

I used frozen rotor model.

In this case, How do i set rotational offset?

Thanks for your guidance.

Edit the definition of the Frozen Rotor interface, and you should see a Rotational Offset parameter to be set.

Hope the above helps,

But i didn't understood your means completely! because English language is not very good. I am grateful that explain more.

When i enable rotational offset, its value is equal to zero.

The default value is 0 [deg]. That is, use the relative configuration as provided by the mesh you imported.

If you set a value different from 0 [deg], the rotor will be moved by such amount, and the relative configuration will change.

what is your exact meaning of "relative configuration"?

I think that Your means about "configuration " is computational domain. right?

According to picture in post 1, I think that rotational offset is eaual to zero. Am i right?
