Heat transfer between fluid-solid-fluid
I am new user and am trying on heat transfer in Fluent .I have three domain (fluid-solid-fluid).I want to make Conjugate heat transfer here . I cant see a -shadow boundary condition of type wall for each interface wall .And I dont open coupled in thermal conditions.I am adding my system project pictures and files.

There should be no interface in your model.
Inner pipe surface BC should be set to wall. Outer pipe surface BC should be set to wall as well. |

Though I'm also not sure why the shadow walls are not appearing. Edit I managed to open the files. The mesh imported by Fluent is already incorrect. So the problem is in the mesh. |

But wista is missing the wall and shadow-wall pair forming the two-sided wall / interface and that is why it is not working. The two-sided wall is built by the mesher and must be present when it is imported into Fluent. |
Yes, in ICEM CFD I created the blocking parts 'PIPE', 'AIR' and 'HOT_AIR', then the 3 mesh volumes are created when the Pre-Mesh in converted to unstruct mesh. Wista, check/uncheck everythig under 'Parts' in ICEM CFD and you will understand the mesh generation process.
