  Hello!
  I am working on CFD for simulation a fan inside a pipe, but I dont want to rotation the fluid direction, I have just wanted to rotate the fan, how can I do it ?
  1) Should I suppress the fan ?, if I dont suppress the fan in meshing may I have a problems because of the fan and the enclosure will be on top of each other
  2) in Setup > Boundary Conditions > fan (intake-fan), Should I use it ?
  
  Thank you so muvh, have a nice day

  These might help. I usually supress the fan but I did not face any issue even I don't. I use the mesh motion option under cell zone conditons. Haven't tried the fan option.

    Thank you Geetanjali
    Actually I watched before the second video, I did not notice fan motion, I think it was fixed and the fluid is movable
    
    Thanks a lot Ms. Alle
