Issue regarding [out of date] mesh in fluent

  I have a geometry in which there is a tube_wall seperating two fluids, making it a case of conjugate heat transfer. When this mesh is read in the fluent, tube_wall appears as interior in boundary conditions. Now when i change this to "wall from interior", tube_wall and tube_wall-shadow are created. All this seems to be in right direction as conjugate heat transfer needs to be solved.
  However, after the wall and shadow wall are created, the fluent figure tab shows " [out of date] mesh".
  I had done shared topology in space claim as well.
  what should I do to resolve this?
  Any help would be appreciated. Thanks.

  Hello,
  
  If you are getting out of date mesh please either replace the mesh with the newer version. Also, are you using Fluent meshing before solution mode? If yes, try to add shared topology in the Fluent Meshing and not in Spacecliam.
  
  I hope this helps.
  
  Thanks!

  You've done the Fluent part correctly. However, manually changing the mesh topology might be an issue in the workflow. If you label the surface as wall-whatever in Ansys Meshing (Named Selection) it should do the wall & shadow pair automatically. Don't forget to give the wall a thickness too!
  We tend not to use Workbench much now. The taught workflow is SpaceClaim/Discovery to Fluent Meshing to Fluent. Code is started from the Start menu or icons. However the older workflow is still used (2d and some parametric studies) and supported.
