Issue regarding [out of date] mesh in fluent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However, after the wall and shadow wall are created, the fluent figure tab shows " [out of date] mesh".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
