    The second column in the table, Launch HV, opens HyperView. Depending on the data type, different windows are opened with the respective diff results.

    For example, for vector results (displacement), four windows open with the magnitude, displacement–X, displacement–Y, and displacement–Z loaded in the different windows. In each window, further details can be viewed.

15. Click the first column of the table to open a new graphics window.

    
    
    Figure 17.

    In the image above, the left window shows a diff contour (Current-Reference) and the right window shows a diff plot in HyperGraph.

    The model and results are pre-loaded for both the current and reference models in HyperView. From the Contour panel, select the data type and data component.

    Control is active for first window

14. Display the results.
    1. In the first window, select a region of interest (element, node, component level) and create a contour.
    2. Run the command ::Displaycontour (reference result contour is also loaded for the selected region).
    3. Run a command to apply a user-defined tolerance for the data type selected ::Applytolerance (otherwise, use the default tolerance).
    4. Run the command ::Diffcontour. Difference contour result are displayed in another window for the selected data types only and are also plotted.

    
    
    Figure 20.

    The first window displays the current model and result, and the second window displays the reference model and result.

    The third window displays the difference in the contour values. If the difference is greater than the tolerance, it is indicated as Fail. Otherwise, displays Pass.

    The fourth window displays the actual diff plots in HyperGraph.

    The data type can be changed and any individual component result can be compared. Tolerance values can be reset to any value and result comparison.

    Comparison for region of interest:

    Part of the model (by window, by component, set of elements, and so on) can be selected in the first window. Using APIs as mentioned above, results can be compared ONLY for the selected region.

In this step, you will compare results from different solver versions ( Radioss or OptiStruct) using HyperGraph.

    Seed Vs TRC

    This is a scatter plot, showing sensitivity for each seed value. This creates a sensitivity corridor that can be used to study the variation or sensitivity of the results for the given model.

    Time Vs TRC

    This shows the following:

    • All Time History (TH) plots across the seed values.
    • Envelope cures (Max, Min, Mean, SD, Mean+SD, and Mean-SD).
    • Statistical curves (Max, Min, Mean, SD, Mean+SD, and Mean-SD).
