Evaluate Heat Flux through plane in CFD Post

hugo17 · October 9, 2012, 05:26

Hi,

I'd like to evaluate the heat flux through a plane which I create using the "Location" tool in CFD Post (within a solid domain) - but Post says "Heat Flux is not available on 'Plane 1'.". Is there any possibility to evaluate the heat flux at positions where no geometric boundary is located?

Regards
Hugo

Hi,

I'm having the very same problem. Any idea?

Regards

Have you figured out how to plot heat flux on a plane?
Thanks in advance

did u select heat flux as result in output control in cfx pre?

How would you have heat flux without a surface transferring heat? It will be zero across some plane in the fluid without a boundary to transfer the heat.

Describe Heat Flux mathematically and you will see what I mean.
