Error when meshing enclosure

    • Matthew Eells

      Hello Guys, 

      I am trying to mesh a symmetric enclosure with a Heat Generation. The mesh is an automatic mesh on the fluid volume and the solid bodies that are inside the enclosure  I continue to get these three errors: 

      1. error:  The mesh translation to Fluent failed due to non-conformal, duplicate, or degenerate mesh elements.
      2. warning: All cell zones in Fluent may be automatically set to Fluid.
      3. warning: Some boundaries of protected topologies have been defeatured.  Right-click on this message and select "Show Problematic Geometry" to see the affected edges.

      I have continued trying ways to fix them, but they have come to no avail. I have found other forum posts about this error and have tried the solutions in those posts. The two solutions I have found are "make sure you share topology shared correctly" and "make sure you do not have any connections". The two questions I have in response to those solutions are: 

      1. How do I correctly complete those two tasks
      2. How do I make sure that I have done them correctly 

      If there are other solutions and any help is appreciated. 

      The pictures of my problem are attached
