Total Heat Flux Calculated by FLUENT

Darron

Users,

wanted: how to access the total heat flux, as calculated by FLUENT, from within a UDF.

context: I have a very simple rectangular (2d) enclosure- 4 walls. I've imposed constant temperatures to three of the sides and a linearly varying temperature along the 4th wall. I'm using the S2S radiation model, and this problem is radiation only- no flow. The walls are of "0" thickness and the enclosure is just air. I want the total heat flux at each cell/face, of the wall across from the one with varying temperature. I know Fluent can calculate the heat flux (you can plot it! or use "Wall Fluxes"), but I don't know how to get to it from within my UDF - is there a way to read it in or calculate it? Another way of calculating it using other vari ables determined by FLUENT? Thank you!
