Solar water heater tube with Conjugate Heat Transfer

I have been trying to simulate a tube of a solar water heater. The tube is made of glass, copper, and water. I have modeled the 3 parts in Autodesk Inventor and imported the model into COMSOL as a .stp file.
I believe that I should be using the Conjugate Heat Transfer Laminar Flow module, but I am having a hard time getting a desirable outcome to my simulation.
In theory, the tube experiences a fluctuating heat flux from the sun, but in order to simplify the model, I would like to just have a uniform heat flux applied to the outside of the glass tube, which would then heat up the copper inside the tube, which would then heat up the water and give it some sort of movement/velocity.
Thank you in advance for any help!
