Heat Distribution
3 Attachment(s)
Hi there,

I'm trying to implement heat flux lines on fluent. I'm new at UDF but I think I'm quite close to achieve this.

I know that the heat distribution can be seen through temperature distribution, because they are penpendicular between each other, but i could't obtain them by only using temperature gradients. Does anybody know why?

In the first picture, I tried to implement the equation: H=\int(rho*Vx*Temperature-K*dT/dx)*dy

But the result should be something like this:

When I tried to use only the temperature gradient, this is what I got:

Any suggestions?
