Getting heat flux
« on: October 22, 2012, 11:30:48 AM »

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.

How do you access that function from within CFX?

Anyone know how to plot heat flux on the wall? So I assume heat flux vs position on y axis?

You can select your coordinates of line that correspond to the surface of the wall. For details of how to plot see the CFX post manual.
