Properties include the component's individual inputs and outputs. They also include hierarchical groupings of properties. It may include inputs from the system's expansion tank, piping, heat exchanger, and pump. The cooling system components themselves can be listed as properties. Their associated input parameters can be listed as subproperties.
Users can traverse an object's property hierarchy using a dot syntax.
The PerlWrapper utility is a tool that enables users to write components as Perl scripts. The PerlWrapper is a good tool for writing simple components, especially conversion routines and small functions, quickly. This manual contains a section that discusses how to use PerlWrapper and provides a PerlWrapper example. A tag is a special word in the comment line of a FileWrapper, PerlWrapper, or ExcelWrapper file that specifies a descriptive field for the component. These description fields are optional when creating a component.
