Domains
Components models can support nature types for several physical domains. Nature types are properties
of conservative nodes (also referred to as ports or terminals) of models. At least one specific nature exists
for each domain. An Across and a Through quantity is associated with each nature. The following table
links the Across and Through quantities for each nature type:
