Fluid domain unable to mesh due to “At least one body has no elements” Error

      Hi y'all,

      I'm trying to mesh an internal fluid domain, and I'm consistently getting the following error:

      "At least one body has no elements in it.  This may be due to mesh based defeaturing of the geometry.  The offending bodies can be identified in the worksheet view on the Geometry folder and suppressed if desired."

      r/ANSYS - Troubleshotting

      When I googled the error code to find past threads, I found that the general consensus was to look at the "Worksheet" tab to see which body has 0 elements/nodes and this is what I see.

      r/ANSYS - Troubleshotting

      I'm sure the problem had to deal with the geometry of the fluid domain. I used the extract volume feature on the inlets and outlets of a manifold, then used the "combine" feature to merge the bodies into one, resulting in the geometry above. Where did I mess up? Is this a meshing problem or do I need to edit my geometry in spaceclaim?

      This could be due to geometry errors or may be due to incorrect sizing defined in meshing. 

      Please check geometry in SpaceClaim. 
      Select geometry in structure tree --> Use right click --> Select Check Geometry. (Or Tools - Fault Detection in DM)
      The geometry should be error free to proceed. 
      If geometry has any errors, please modify/recreate geometry at those places. 

      In meshing, please check sizing. Please corect min sizing. Also try to make mesh based defeaturing off. 

      Regards,
