- Provides capability to compute environmental and radiative heat loads directly, bypassing Oppenheim’s (radiosity) and Gebhardt’s methods.
- Allows for the simulation of interaction of radiation with participating media, i.e., absorption and scattering of light through a semi-transparent solid.
- Permits
simulation of advanced optical properties:
- Direction-dependent emissivity.
- Bidirectional reflectance distribution functions (BRDF).
- Fully compatible with other TMG radiation analysis methods.
