13.4. Post-processing an Operating Point Case

When you postprocess an operating point case in CFD-Post:

  • The Cases and Report objects each list the defined operating maps for each loaded operating point case. The Cases object also lists, for each operating map, the data series objects defined in the operating map. The Report object also lists, for each loaded operating point case, the operating point parameter table, which is essentially the operating point input parameter table (shown in CFX-Pre) with added columns showing output parameter values.

  • The Operating Points Viewer is available to show, for a given case, the operating point parameter table and an operating map based on that table. For details, see CFD-Post Operating Points Viewer in the CFD-Post User's Guide.

    As for other charts, you can show an operating map in a separate window by right-clicking the operating map in the Outline tree view and selecting Show in Separate Window.

  • To switch to a different operating map, right-click an operating map object in the Outline tree view and select Edit.

  • You can create new operating maps by:

    1. Do either of the following:

      • Right-click Cases > [case name] > Operating Maps and select Insert > Operating Map Chart.

      • Right-click Report > Operating Points > [case name] and select Insert > Operating Map Chart.

      The details view for the operating map appears.

    2. Configure the settings as appropriate.

      For details, see Operating Maps in the CFD-Post User's Guide.

    3. Click Apply.

  • You can check the quality of the response surface as follows:

    1. Right-click Cases > [case name] and select Edit.

      The details view for the case appears.

    2. In the details view, on the Operating Points tab, observe the tabulated quality metrics for all of the generated response surfaces. Each row of the table corresponds to one response surface for one output variable. The quality metrics table gains a new row every time a new response surface is generated.

      Note that a response surface for a given output variable is generated only when you make an operating map that uses response points for its data source and that plots the output variable or uses the output variable as a chart axis.

    The same table of quality metrics appears in the Report object and the Report Viewer.

    The quality metrics are the same as those used in Ansys DesignXplorer. For details, see Goodness of Fit for Output Parameters in a Response Surface in the DesignXplorer User's Guide.
