Heat FLux through wall

thomasteve · October 22, 2012, 07:33

I have just started to use CFX. I am trying a few test cases as part of an assignment. One of them involves a cylinder inside a rectangular duct. The cylinder is heated while the duct is cooled. I have done simulations and it all works out. But what I cannot find out is how to find the heat flux as from one of the walls. I though you could use functions as I found out the mass flow rate for another example before. But the variable heat flux does not appear. Any help on how to finish this will be appreciated.

are you using CFD POST to see your results?
You could try making a contour to display "wall heat flux" or "Heat flux" you can try to display these contours on the fluid interface side, or the solid interface side. It should work with one of these combinations.
