Executing the Model and Viewing the Results

Once you have built your model and configured all the components, you can execute the model to view the results.

  1. With the model open in the Design Gateway, click the button.

    By default, the History tab in the Runtime Gateway opens, and the simulation code runs.

    Note: If you want to change the tab that opens by default in the Runtime Gateway, see Setting Execution Preferences.

    From the History tab, you can see that the ApproxLoop component obtained good solutions with respect to the objectives (minimizing the loaded weight and stall speed, and maximizing the range). Many of the bounded variables reached their lower or upper bounds, meaning that the solution has been constrained by the allowed variability of the inputs. The starting point for the analysis had the following initial values:

    Parameter Initial Value
    LoadedWT 2340
    StallSpd 78
    Range 781

    After the ApproxLoop component executed the simulation process flow multiple times, the best solutions were found:

    Parameter Value
    LoadedWT 2071.8
    StallSpd 73.425
    Range 643.05

    The model's objective value was reduced from a starting point value of 0.780 to 0.404, which is almost a 50% improvement.

  2. Create a history graph for the StallSpd parameter to chart the progress through the simulation process flow:

    1. Click the Graphs tab.
    2. Click the Graphs button.

      The Graph Chooser appears.

    3. Select History Graph, and click Next.
    4. Select Stallspd, and click Finish.

  3. You can move your cursor over the points to see the different values.

  4. Create a history graph for LoadedWT.

  5. Create a history graph for Range.

  6. To view all the runs, see Viewing the Benefits of the Approximation.
