  Dear all,
  
  I'm doing simulation of flowing in micro-channel PCHE (counter flow). I'm quite confuse about solid-fluid interface.
  
  As a figures, adjacent cell zones are different between them.Which one is correct?
  
  (I thought interface should be adjacent solid domain and interface-shadow should be adjacent fluid domain)
  
  And when I created name selection with interface name, ANSYS Fluent will create shadow zones automatically, is that right?
  
  Thank you

  That is a coupled boundary: leave it as it is.
