<h1>MSCPatran Component</h1>


<table>
	<tr>
		<td>Description:</td>
		<td>This model demonstrates the MSCPatran component being driven by an Optimization component.  The simulation
		is a linear static stress analysis of a cantiliver plate.  Patran is used
		to prepare the Nastran input deck and extract output parameters.  An optimization problem is defined
		to vary the thickness of each plate zone in order to minimize the mass of the structure subject to maximum
		Von Mises stress constraints.  A stress ratio optimizer is selected for maximum efficiency on this class of
		problem.  Isight parameters are renamed in the Optimization component to conform with the name matching convention
		of the stress ratio optimizer.
