Make a Goal Optimization Study

Allows you to perform a set of calculations varied only by a selected variable parameter in order to find an analysis (i.e. a specific value of the dimension or parameter) where the selected flow parameter (defined as a goal) will be equal to the specified target value.

Procedure

  1. Open the Parametric Study  dialog:

    • On the ribbon, click Flow Simulation > Solve > New Parametric Study.

    • In the menu, select Tools > Flow Simulation > Solve > New Parametric Study.

    • In the Flow Simulation project or analysis tree, right-click the project name and select New Parametric Study.

    • In the Flow Simulation project tree, right-click the Parametric Studies item and select New.

    • In the Flow Simulation analysis tree right-click the desired condition item or goal and select Parametric Study.

    The Parametric Study pane appears at the bottom of the screen.

  2. In the Parametric Study Name input field, type the desired study name.
  3. If you have a previously created parametric study for the current project, click Load Study  and select the *.fwps file.

    If you want to save the current parametric study settings, click Save Study As , then select the destination directory and specify the file name.

  4. Select Goal Optimization  study to vary only by a selected variable parameter in order to obtain a specific parameter value at which the selected goal of interest will be equal to the specified target value.
  5. On the Input Variables  tab, select an input parameter to vary.

    Then specify values denoted an admissible variation range for the variable parameter.

    The study will search for the input parameter value providing the desired value of the selected flow parameter specified as a goal

    See “Input Variables” for details.

  6. On the Criteria  tab, select the target goal and specify its value to be compared with the calculated goal value and the permissible range of variation.

    See “Criteria” for details.

  7. On the Output Parameters  tab, select goals and plots of interest.

    See “Output Parameters” for details.

    The selected goals, graphic plots, XY plots and point, surface and volume parameters appear on separate tabs as the Compare tool (see “Compare Tool” for details).

    In addition to the standard Compare actions you can remove unnecessary design points by using the Filter of Input Parameter  dialog.

    On Goals tab you can also edit the list of displayed goals by using the Filter of Goals  dialog.

  8. On the Scenario  tab, specify Study Options to define finishing conditions (see “Study Options” for details).

    Then click Run  to start the study.

    See “Scenario” for details.

  9. If you want to save all output images and plots to the selected folder by clicking Save Results to Folder .
    Note:

    Note, that the previously saved plots and images will be overwritten.

  10. Click OK  to save the current parametric study to the active project.

Results

The new Goal Optimization item appears under Parametric Studies in the Flow Simulation project tree.

To edit definition of an existing Parametric Study, in the Flow Simulation project tree, double-click the Parametric Study item, or right-click it and select Open.
