Use the Iso tool to display single iso values (iso surfaced for solids or iso line for
shells) dependent on results data.
The result data used to calculate the iso surfaces or values can be specified
independently of the result data selected in the Contour panel, even though most of result
selection options are similar to the contour options. Since an iso value is independent of
contour results, for OptiStruct design space optimization results,
you can apply a single iso surface for density, then contour stress results on the generated
iso surface. Combining contour, iso value, and transparent global boundary geometry (shortcut
key "T") is an excellent way to investigate hot spots of result data. By varying the iso value
slider bar, you can easily observe critical areas. From the View Controls
toolbar, click Iso Plots
