This dialog appears by right-clicking on an input stream (bulk or discrete) and selecting Initialization Options from the context menu that appears. It is used for specifying the initialization settings of an input stream.
Having selected the ‘Auto-Initialize from Other Stream’ option you may set whether to initialize the stream from another stream in the same file or from another file.
● If you select to initialize the stream from another source click on the Browse/Select File (
) button to browse for the source file and then select the stream from the list.
● If you choose to use a stream from the same file, select the stream from the list and click on the View Stream/Equipment Contents (
) button to view the Stream Data Summary Dialog. The stream data can be viewed for source streams of another file as well.
The user may choose to initialize the following:
● Total Mass Flow
This option requires that the source and destination processes and streams are compatible (You can not initialize a bulk input stream with a discrete stream or vice versa). This option may appear unchecked and disabled if the input stream’s flow you want to auto-initialize is Auto Adjusted (see The Input Stream’s Auto-Adjustable Flag).
● Multiplication Factor
The total mass flow of the destination stream may differ from the source stream by a multiplication factor. Default value: 1.0.
● Composition
It appears checked and disabled when the total mass flow is initialized as well. You can not initialize the mass flow without initializing the mass flow. However it is possible to initialize the composition only without the mass flow.
● Density/Thermo Data
Is dependent upon the composition. Cannot initialize density/thermo data without the composition.
● Temperature
Initialize the temperature of the input stream.
● Pressure
Initialize the temperature of the input stream.
Under ‘Before Performing M&E Balances...’, the user may set to Never Auto-Initialize, Always Auto-Initialize, or be Asked from the program to initialize the input stream’s contents before the Mass & Energy Balances are performed.
Finally by checking the option ‘Apply Auto-Initialization Upon Closing this Dialog?’, the input stream’s contents will be initialized as soon as you exit the dialog.
