KR413: How can we compute radiation heat rate on an interior surface using UDF? (Solution ID: 669)
|
The UDF loops through all DO directions for each face on the surface, and depending on the s dot n sign it picks up the radiative intensity "upstream" of the surface so that only incoming radiation on either side is considered. For each DO direction there is incoming radiation from both sides so that in the end the integral computes a net quantity. |
