Calculating outlet temperature pipeline

Background: I am utilizing CCM+ as part of a college level project, and I have very limited experience with CCM+, infact I have barely had time to finish some of the tutorials and have fooled around with the program for a bit in order to familiarize myself with it. My apologies in advance if the following is something I should have figured out myself, but I didnt and hence seek some guidance from this forum.

Problem: I am trying to simulate seawater flowing through a buried pipeline in a hot climate, and wish to calculate outlet temperature, as a result of heat conduction through the soil and pipeline.

I have generated what seems to be a solid mesh and applied adiabatic walls at a given distance from the pipe wall, with a fixed convection rate from the surface to simulate heat transfer from radiation and convection - this is obviously a very simplified approach, but as stated I do have very limited CFD experience..

Now what seems to be the problem for me is choosing the appropriate physics models to the continua, because as it is I am unable to choose Temperature as an output as was done in the "heated fin" tutorial.

Is CCM+ actually able to solve for temperature in such a simulation (3-d, fluid surrounded by multiple layers of solid), and if not do you have a suggestion for an alternative approach to the problem?

My goal with the simulation is to verify a theoretical model used to estimate outlet temperature in a long pipeline. This estimation will be rough, and not account for change in ambient temperature etc.

Thank you in Advance.

How are you trying to measure the temperature? Is it an Area averaged report from the outlet?

Thank you for your swift reply.

Ideally I am looking for an output similar to the one from the heated fin tutorial - I would guess an area averaged report from the outlet would suffice to estimate the average outlet temperature after a given distance.

Again I apologize if the question may seem trivial, but this is due to my lack of experience with CFD.

right click on Report, new Report, Area Averaged.
rename it as you like
in the property window you chose
scalar: temperature
parts: your outlet boundery
units: C or K

right klick on your new report: run report: your value will be displayed!
you can also create a monitor from your report to save your report value at each iteration!
