Dear all,

I am going to simulate a 5 deg. cut of a axisymetric channel.
However i wnat to know that how can I apply different rotational speeds to different walls of the model

wall boundaries have a tangential velocity specification property and this allows rotation or translation

the help is pretty good on this subject so i suggest you might read it

you will learn that one option is to choose local rotation rate and then a new values node is added with inputs for coordinate system, axis origin and direction

and then to be sure you should add those walls to a vector scene and observe the vector directions and magnitudes
