Hi, I've been a long time lurker/searcher on these forums but I can't find a straight answer anywhere to my question (which I think should be simple...):

How do I see/get-the-data-into-a-spreadsheet the radiation heat flux distribution and radiation intensity distribution (for each direction) in my 2D plane-parallel discrete ordinates problem?

I'm working on a project for school and this is the first time I've ever used ANSYS, but I'm fairly certain I have set up and solved the discrete ordinates method correctly; I just can't get the results I need... I can plot and retrieve incident radiation, G, in a spreadsheet, but I need the intensity and heat flux distributions.

I have 2 plane-parallel black walls, separated by a 1cm distance, with that space filled with a participating solid media. I made the walls 10cm long, and then defined a periodic boundary condition on the sides.

Thanks for any help/advice, if any more info is needed, let me know!

Hi kozzney,

1. In order to get the surface heat flux of certain boundaries, you should plot them using the XY Plot menu, selecting Wall fluxes... for the Y axis Function. Define the specific function below (e.g., Radiation Heat Flux or otherwise), choose the X Axis Function and the desired BCs (note that for the Curve Length option for the x axis, you can choose a single BC at a time) and check the Write to File option. Click Write... and define the file name. You will get a text file that is readily imported to a spreadsheet.
2. AFAIK, you have no direct access to the intensity field. Maybe this can be done by UDFs. Check the manuals.
3. I referred above to the DO model. It may be different with other radiation models (S2S, DTRM,...).
