Similar to the Temperature inserted along the first path, now insert Directional Heat Flux results along Path 2. (Right Click) Solution > Insert > Thermal > Directional Heat Flux. Choose Path for the Scoping Method, set Path 2 for the Path and Y axis for Orientation, as seen below.
{neww(Click ) Solve, , and ANSYS will find the Directional Heat Flux on the line y=0m as a function of x position. We would like to find the total heat flux through the bottom by integrating the flux along that boundary. To do this we will export the data to MATLAB and perform a numerical integration. Right click in the tabular data displayed in the lower righthand corner of the screen. Select all (Ctrl+A), right-click and select Export. Save the file as "qy_bot.txt" in your MATLAB working directory.
