Radiation UDF Macro

      Hi all

      I want to access incident radiation for each cell in a UDF file for my work, but I can't find any UDF macro to do that.


      Is there anyone that knows what should I do?

      Surface facet or volume cell?  Which radiation model?

      sorry!

      Radiation model is Discrete Ordinate (DO)


      Volume Cell

      If you do not find that in the customization manual then pretty sure that is not supported. As ANSYS Staff, I cannot tell you which macro is required to access that.

      It's a non standard macro, and unfortunately isn't in DOC. Fortunately it's in here:

      Which makes it public domain.  I'll leave you to read the thesis: it's a storage macro that you're after.
