Comments
- The number of external links in Radioss model is not limited. The only restriction is that different links should not contain common nodes. Each link defines a distinct interface between current model and external world.
- The links do not specify the corresponding domains. Each model is independent and may be replaced by another one having the same frontier nodes. This approach allows a modular approach to modeling, for example testing runs with equivalent domains with different mesh size (multi-grid approach).
