CAE与测试结果之间的相关性是非常战略性的活动。它提高了对产品的发展的信心。Altair’s Virtual Gauge Director (VGD) is a combination of customized software and services that enable engineers to extract the results at the exact position of the strain gauge as in the test lab, interpolate the results at an identified CAE location, compute results in the local coordinate system of the gauge, and give a correlation index confidence. The Director can also be used to interpolate stress or strain values at any placement in the model.
