<h1>Subflow Parameter History Feature</h1>

<table>
	<th colspan=2>Subflow Parameter History Example</th>
	<tr>
		<td>Description:</td>
		<td>This model demonstrates how you can store a history of any subflow output parameter
			(scalars or 1-D arrays) in a resizable array inside the process component. The root
			component is a DOE. In the subflow there is an Excel component that demonstrates
			an analysis of an I-beam, and a Script component that creates a very simple report
			file in the working directory. This file is saved in a file parameter of the Script
			component.<br><br>
			To access the feature, open the properties dialog of the process component (DOE), then
			click on "Prologue/Epilogue..." button to open the dialog with Prologues and Epilogues
			of the process component. The last tab of the dialog gives access to subflow parameter
			history mappings.<br><br>
			When a subflow parameter is selected for a history mapping, a mirror parameter is 
			created in the process component and the subflow output is mapped into it. To complete
			the history mapping, a 
			resizable array for storing the history of the subflow parameter must be selected or
			created.<br><br>
			After the model is executed, open the "Parameters" tab in the Runtime Gateway, select
			the option to display the component's parameters (instead of subflow parameters). Examine
			the arrays History-of-Deflection, History-of-Stress, All-Reports. They should contain the
			history of corresponding parameters Deflection, Stress, Report-file from the subflow.<br>
