Parameters

compIds  Object

Reference value to the list of component IDs. A reference to a System.Object containing a String array marshalled from a COM Object.

formulae  Object

List of component formulae. A reference to a System.Object containing a String array marshalled from a COM Object.

names  Object

List of component names. A reference to a System.Object containing a String array marshalled from a COM Object.

boilTemps  Object

List of boiling point temperatures. A reference to a System.Object containing a double array marshalled from a COM Object.

molWt  Object

List of molecular weight. A reference to a System.Object containing a double array marshalled from a COM Object.

casNo  Object

List of CAS number. A reference to a System.Object containing a String array marshalled from a COM Object.

Returns the list of components of a given property package.

In order to identify the components of a Property Package, the Executive will use the ‘casno’ argument instead of the compIds. The reason is that different COSEs may give different names to the same chemical compounds, whereas CAS Numbers are universal. Nevertheless, GetProp/SetProp... will still require their compIds argument to have the usual contents ("hydrogen", "methane",...). Be aware that some simulators may have a limitation on the length of the names for pure components. Hence, it is recommended that each identifier returned by the compIds argument should not contain more than 8 characters. See notes on Description of component constants for more information.

If the package does not return a value for the ‘casno’ argument, or its value is not recognised by the Executive, then the compIds will be interpreted as the component’s English name: such as "benzene", "water",... Obviously, it is recommended to provide a value for the casno argument.

The same information can also be extracted using the ICapeThermoPropertyPackage GetComponentConstant method, using the casRegistryNumber property identifier.
