In particular, the difference between setting the enclosure type to ?perfect? vs ?open?. My current understanding is as follows. In a perfect enclosure, all radiation emitting from every surface adjacent to the enclosure ends up striking the other surfaces and none is lost to the environment. In a open enclosure, if ANSYS determines that a particular ray of radiation would not strike any of the other surfaces, that radiation is treated as ?ambient? radiation and is radiated off the environment. Is this a correct understanding? n

The model is described in both the Fluent User's Guide and Theory Manual n
