  I have a pump intake model with approximation pipes, entrance to the sump and 4 pipes as outlet.
  
  The Fluent is showing
  
  Note: zone-surface: cannot create surface from sliding interface zone.
  
  Creating empty surface.
  
  I can see internal surfaces that do not appear, and many interfaces. I would to to have only the named surfaces created as boundary conditions.
  
  Can somebody help me with this.
  
  I already
  
  - Create a Part of the internal fluid that I am using.
  
  - Put Automatic in the Shared Topolgy Method (that produced a reduction in my mesh quality)
  
  - Reset the Fluent Setup before starting.
  
  Help.

  I am currently doing an oil splash analysis for gear casing. If I initialize the solution I get this error : zone-surface: cannot create a surface from sliding interface zone. Creating empty surface. What is the reason?
