Default Fluent View Factor Exportation
Posts: n/a
I am currently working on an enclosed radiative heat transfer problem with complex geometry. All surfaces in the enclosure have set temperatures and the media is nonparticipating. My sole purpose is to obtain net radiative fluxes to specific surfaces. I am currently using Fluent with S2S radiation model and only solving the energy equation. Is there a way to export the view factors calculated using the S2S model so that I do not need to solve the problem within Fluent? Thanks for any help that anyone can provide! Scott

you can open that s2s.gz file, take the matrix of view factors and use wherever u want to use. Fluent writes view factor at every node. I m not sure how accurately fluent calculates the view factor. U just draw a simple geom with very only one grid point (i.e. a normal geom, no mesh), do hand calculation & check with Fluent first.

I have looked into this, but it is difficult to keep track of the separate faces with a complex geometry where I do not have previous knowledge of the view factors. Thank you for the suggestion though.
