Postprocessing geometry display

  Hello all,
  
  I'm curious about the geometry display on the postprocessing section, fluent software. Here is the image on the postprocessing
  
  On the spaceclaim I draw the cylindrical shape for the draft tube geometry but on the post processing section I saw it like a prism shape,
  
  so my question is, does the simulation calculate as the cylindrical shape ? why it appear as the prism shape ?
  
  Thank you all,

  Hello,
  
  You might have defined some boundary zone in Fluent at that location and that is why you see those prism shape faces.
  
  OR
  
  You might have missed meshing at that location.
  
  Please cross check your boundary zones in meshing and in Fluent.

  Hi,
  
  Thank you for replying. I already identified the draft tube geometry and name selected the draft tube for mesh sizing (1e-2), for the boundary I set it as stationary wall.
  
  Any recommendation ? I still don't know why it appear like this and does it calculate as the cylindrical shape tube or prism shape tube ?
  
  Best,

  Hi,
  
  can you please insert the image of boundary zone names you can see in Fluent.

  Hi,
  
  sorry for late reply I have been waiting for the calculation.
  
  I had tried to mesh sizing again with more precisely, for now I'm able to get the cylindrical draft tube on the post processing.
  
  Here is my set up on wall stationary for the draft tube. Another curious for my draft tube interior boundary, fluent auto set as interior do I need to change it in to wall ?
  
  Thank you,

  Hello,
  
  Good that you can get that as cylindrical.
  
  If you have fluid on both side of a boundary zone, fluent will set it as interior. If you want you can change it to wall.
