Analytical Boundary conditions

Hi ,
I want to simulate the transient heat transfer (conductive ) in a infinite domain surrounding a pipe in which there is a fluid flowing. I don't want to resolve the fluid flow, instead I want to use the analytical solution based on the inlet temperature and the temperature of the wall in the pipe to calculate the flux boundary for the heat transfer equation.
The pipe will then be discretized in axial direction,
Can I do this in comsol or do I have to also discretize the flow?
thankful for some advise!

You can use nearly any analytical expression for use in your boundary conditions. This includes heat transfer coefficients or the velocities in your pipe or whatever. It strongly depends on what you want to do and what you already know about your system. check the doc.
Hope this helps.
