Is anyone aware of a 3rd party or commercial software package that can compute 3-D surface-to-surface radiative exchange factors, which can then be output to the file radi.dat? If so have you successfully input the factors and then run the problem in PHOENICS?

I remember asking LOs-Alomos for some view factor code that they wrote which they gave out as freeware, but this was years ago. I could then bolt this into the code I was using at the time. The gentlemans name was Prof Shapiro and I think the code was called facet, maybe they still have the code and would still give it away.

phoenics does have 2d view factor calculating code
