	<tr>
		<td>Description:</td>
		<td>This example uses Isight Abaqus component to illustrate a NoiseAnalysis scan. In
		this simple cantilever boss model, the effect of modifying the span is studied. As
		the span increases, it is expected that the maximum stress and displacement should
		also increase. After running the NoiseAnalysis using BossNoisy6.9-1.cae, a non physical response
		is observed with stress and displacement sometimes increasing and sometimes decreasing with
		increasing span. BossNoisy6.9-1 was created with default mesh seeding and C3D4
		tetrahedral elements, whereas BossCorrect6.9-1 was created with C3D8I hex elements and a more
		refined mesh seeding. These are more appropriate for the bending loads present in this model and
		produce accurate and non-noisy results.
