How can I manually define the interfaces for a natural convection within a channel simulation?

  Hello everyone,
  
  I am trying to simulate natural convection within a channel. The image below shows a zoomed in image of the channel geometry.

  Hello The issue with the mesh is because of the conformal mesh at the interface, as you have very refined mesh at the fluid and coarse one at the solid. Either you can reduce the difference in the mesh sizing in both the region or else you can use a poly mesh which is also good as a hexahedral mesh, instead of tetrahedral mesh.
  I would recommend you to use share topology in spacecliam and make the interface conformal so that they will be automatically coupled and you dont need to control them manually.
  Where do you intend to apply the heat flux condition? Can you be more specific about that?
