How can I couple 2 temperatures in different physics!? I have laminar flow and heat transfer in fluids Modules and one extra PDE Eqn. I want to have the same Temperature in both PDE and Heat transfer equations. But comsol doesn't let me have the same T in PDE and I have to enter like T2 instead. I want the temperature in the first equation to be equal to last equation.
This website can help you. Good Luck

Within the "Multiphysics" module there is an option for "temperature coupling". Here you can select the physics you want to couple. The "multiphysics" module may or may not appear automatically when two physics are added; I think this depends on the version of Comsol you are using. I hope this helps.
Dear Roman, I tried to use your idea, but I couldn't figure it out how. Your help is so appreciated. Thank you.
Dear Richard,
I have tried your idea earlier, but unfortunately, it doesn't show the physic I want to couple to choose. I don't know why!?
Hi Siamak, This may not be applicable to your problem, but try using the heat transfer in solids module instead of the heat transfer in fluids module and couple this with the laminar flow module. Also, for my problem I had to add in the non-isothermal flow sub module from the multiphysics module.
I had the same thought that Roman, you should try to post your problema in the forum in COMSOL website, i used it and have fast and good replies
Grettings ans good luck
