Accessing the outlet value to apply in the inlet boundary

I need to set up the inlet boundary condition (temperature) in the conjugate heat transfer analysis with larminar flow. However T of inlet (fluid) should be like this:
Tin = Tout + 3 K (at every time step)
The scenario is that the water from outlet is boiled and then re-injected into inlet.
What variable do I use to get outlet temperature?
Is there any function to access boundary values in the variable expression?
Thanks.

have you got your model up running, in case I believe this is what you wanted no ?
it's a 4.3a model

Good luck

I think i have exactly the same question Lee had before. And I have tried the model provided by Kjelberg and really get some understanding about this question. However, I still have a question, that is, at the begining of the simulation, I think the Temperature at the inlet and outlet should be in consistent with the initial value. I'm wondering how to keep the consistency of the Temperature at the inlet and outlet with the initial value.
Thanks
