Heat Rate Source
This feature models a two-port source component of the thermal system. It connects two nodes, by creating a difference in the heat rates of its two connecting ports. It models a heat source or sink in a domain.
It adds equations for the heat rates Pp1 and Pp2 and the temperatures Tp1 and Tp2 at the connecting ports p1 and p2 of the component, and defines the heat rate P.
Identifier
Enter a Component name for the radiative heat source. The prefix is P.
Node Connections
Set the two Node names for the nodes connected by the radiative heat source.
Component Parameters
Set a value or expression for the heat rate Psrc.
Results
