Summary: Enable the approximate (flux-based) radiation model.
Flag:
rad_model_1 A
A = 0: use the current radiation model, (default)
A = 1: use an older radiation model
Description:
The current radiation model uses a true view factor calculation and supports reciprocity. It is more accurate than an earlier model, but is also more resource intensive.
Use this flag if you need an approximate radiation solution, but do not have the computing resources (or time) to use the current radiation model.
Note that this model does not compute true view factors nor does it support reciprocity or symmetry.This model does not produce radiation results that are as accurate, but is useful for producing an approximate solution.
