Hi,
I am trying to simulate a fluid flowing through a pipe with external heat sources and I would also like to include the conduction due to the pipe wall's thickness in the calculations. Could anyone help me with this? This is what I initially tried to do but I don't think it is enough to represent it.
Thank you in advance for your collaboration.

You are VERY close.
Try either of the following, depending on what type of heat source your have:

Since Simscape blocks are "lump" models, having two conductive components and one thermal mass is a more accurate way to represent the temperature differences at the two sides of a wall and the wall itself, as a lump mass. This way, you can have a hot temp on the left, cold on the right, and a "warm" wall in the middle.
All this was assuming the thermal mass of the wall/roof/window is important enough to be modeled. If for your application you believe it's OK to ignore the thermal mass, you can use just one conductive element to represent the component.
