Meshing a solid in fluent

  Hii, I am working on a problem where I extracted the fluid volume from "volume extract" in ANSYS SpaceClaim. There is a hollow space where a solid component (Contact tube and electrode) is supposed to be present. They have been assigned as walls (fluid is not supposed to flow into it) I want to ensure that conduction takes place and do the solid properties get assigned to those walls. How to check it. Is it really necessary to mesh that hollow region so that fluent applies the solid properties to it? I have attached the geometry for reference
  
  Thanks in advance

  If you want the solid to be there you need to mesh that volume too. You set it as "solid" in Fluent and all it'll so is conduct heat.

  Hello sir, I created a mesh and changed it to volume too. But I am getting something called "Shadow" for an already existing named selection and also I am not able to input electric flux while using the electric potential method, it only shows contact resistance. Before there was an input to the electric potential method. Also, I keep getting this message "Slitting wall zone 5 into a coupled wall". I have attached the image for reference.
  
  Thanks in advance.

  Wall & wall-shadow are the different sides of the same surface (think of a sheet of paper, you have "top" and "bottom" where one side has writing on it and the other doesn't).
  
  If you were adding a flux to that wall previously you may struggle as the wall is now internal: you'd typically add a thermal flux to the solid zone in this case.
