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 heat rate source. The prefix is P.
Node Connections
Set the two Node names for the nodes connected by the heat rate source.
Component Parameters
Set a value or expression for the heat rate Psrc.
Initial Values
Set user defined values or expressions for the Initial temperature at node 1, T1,init, and the Initial temperature at node 2, T2,init.
Results
Select appropriate options in the Add the following to default results in order to include the following global variables (space-independent) in the default plots:
•
 Heat rate
•
 Temperature at node 1
•
 Temperature at node 2
