Hello everyone!
I am trying to simulate a double pipe heat exchanger in Ansys student. I have used the k-epsilon (2-eq) model, realizable with enhanced wall treatment. On boundary conditions, I have inlet (cold inlet & hot inlet), Internal (interior cold fluid, interior hot fluid, interior-inner_pipe and interior-outer_pipe), outlet (cold outlet & hot outlet) and wall (adiabatic wall, wall cold fluid inner pipe, etc.). My major problem is when I am computing or calculating, the interior cold fluid and interior hot fluid do not appear. I would like to plot a temperature and pressure change as the fluid flows from the inlet to the outlet. What should I do?

You may want to initialise from hot (or cold) inlet and then use Patch for the other channel. If you're wanting to plot contours etc look at isosurface & planes: they're widely used in the tutorials that are in Fluent's Help system.
