  Hi all, I am trying to simulate a conjugate heat transfer simulation of a duct with two materials and constant flow of ethylene glycol through it as a cooling fluid. The duct has inner walls of aluminium and an outer copper wall with a component generating 25W with a maximum temperature of 95'C on the bottom of the duct.
  When I run it for some reason I am not getting any heat transfer across from the component to the cooling fluid, the copper plate is being heated but there is no conduction into the aluminium plate or convection into the cooling fluid. I am not sure if it is something to do with the boundary conditions I am using, do you reccomend anything I can do to fix this?
  Thank you in advance.

  Hi,
  I suggest you to check the quality of your mesh, especially near the interfaces between different materials and in regions where heat transfer is expected to occur.
  Ensure that the properties of the component generating heat are correctly specified in your simulation setup. And also double-check the location and orientation of the heat source within the duct geometry.
  Thank you
