You can save this plot to a file by selecting "Image to File" in the top toolbar as shown in the snapshot below.
We will view the heat flux as vectors. This will tell us the direction of heat flow within the geometry as well as at the boundaries In order to plot the heat flux vectors, select Solution > Total Heat Flux from the tree on the left. Then (Click) Vectors, near the top of the GUI. The sliders in the top bar can be used to change the size and number of vectors displayed.
At this point, the heat flux vectors should appear similar to the image below. Take a minute to think about whether the heat flow directions at the boundaries match what you expect.

We’ll plot the heat flux crossing the bottom surface as a function of x. The steps involved are:

To integrate the heat flux along a boundary where temperature or convection is specified, drag the boundary condition in the tree to the Solution branch. This will add a "reaction" in the Solution Branch. Right click on this and select Evaluate All Results.

The overall heat fluxes are reported as “reactions” at boundaries in ANSYS. This terminology comes from analogy with structural mechanics and is explained in the video below.
