  Hello all.
  
  So I have created a model, a room where air enters from an opening in the middle on top and exits on the sides, the air goes through an air diffuser which is a disk with multiple holes with same diameter, I run the model and everything goes smoothly and I get convergence.
  
  The problem is when I look at temperature contours of the ceiling, its supposed to be same on each side since the holes are exact boundary conditions, but what I get is is not uniform contours. What could be the cause, here is a picture of what I get.
  
  Thank you guys!

  Hello,
  
  Can you please include the color bar so that there is some context to the colors? Also, was this a steady state or a transient simulation?
  
  Thanks,

  is it 2d or 3d?
  
  what is residual criteria used?
  
  can you put some arrows to show inlet, outlet and flow direction.

  sure thing let me add it, its a steady state case.

  its a 3d case, its like you are looking at the room from the top, and the circle is the air inlet, I was to study the temperature distribution on the ceiling, and these four edges have same B.C
