Hello there,

I asked myself, because I worked before on Autodesk CFD and there is an option about "Free spinning", whether in CFX is a similar option. For example I want to simulate a water turbine and want to know which rotation speed the turbine gets through the flow, which option can I use?
In Autodesk you can give the inertia and then the rotation speed will be one of your output values.

When I want to simulate a turbine and I give an angular velocity I thought it will work as a pump!

Maybe someone can explain whether I am wrong and whats the best way to simulate such things.

Thank you !
