  Hi Support,
  
  If I'm trying to simulate the effect centrifugal fan can this be done by using the rotating wall condition or is this not possible in Discovery?
  
  In the model attached I have a simple volume with a rotating wall on a cylindrical face.
  
  Have you any examples of a rotating wall in a model?
  
  Help files aren't that useful and I'm not sure the results I am getting in this example are functioning as expected.

  Hello Tim Dukes
  
  Swirling flow only adds a rotational velocity to flow inlet.
  
  Let me check the model you have shared and get back to you.

  Apologies for the misunderstanding. I thought you were simulating Swirling flow.
  Rotating wall gives the specified rotational velocity on the wall face.
  I don't think it is a good approximation for a centrifugal fan.

  Hi Subashni
  
  Thanks for looking I have found some examples of rotating walls
