Allows you to begin a parametric analysis.
Note that some of the options change depending on what you are creating.
Learn more about parametric analyses with Parameterization Basics.
For the option: | Do the following: |
|---|---|
Model | Enter the name of the model to simulate. |
Temporary Settings | Specify one or more Temporary Settings Files(.tsf) files. Property values contained in the file(s) will be applied before starting the simulations and then reverted to their original values immediately after the simulations finish, even if some of the simulations fail to complete. Note that this field is only available if the Temporary Settings capability has been enabled from the AView-Preferences section of the Adams Registry Editor. |
Simulation Script | Enter the name of the simulation Script to use. |
Study a | Select either Measure or Objective to define the type of objective you are using. ■If you selected Measure, select Last, Minimum, Maximum, or Average from the pull-down menu, and then enter the name of the measure in the text box. ■If you selected Objective, enter the name of the objective in the Objective text box. Optimizations are limited to one objective. You can monitor more than one objective in a Design study or Design of experiments (DOE), however, by entering more than one name separated by a comma. |
Note that each type displays some different dialog box options. Learn about options available for all types. | |
Design Study | |
Design Variable | Enter the name of the design variable that you want to vary. |
Default Levels | Enter the number of levels (values) you want to use only if you specified a range for the design variable. ■If you specified a range for the design variable, Adams View uses equally spaced levels across the range. You specify the number of levels in the Default Levels text box. ■If you specified a list of values for the design variable, Adams View runs a simulation using each value, ignoring the Default Levels text box. |
Start | Begins the simulation. After you select Start, Adams View runs a simulation for each level of the design variable. When the simulations are done, Adams View returns the variable to its original value. |
Design of Experiments | |
Design Variables | Enter the name of the design variable that you want to vary. |
Default Levels | Enter the number of levels (values) you want to use only if you specified a range for the design variable. |
Trials defined by | Select either Built-In DOE Technique, Direct Input, or File Input from the pull-down menu. ■If you selected built-in techniques, use the DOE Technique pull-down menu (see below) to select the technique. If you want to check that the variables have the same number of levels and display the required number of runs, select Check Variables, Guess # of Runs. ■If you selected direct input, enter the number of trials (simulations) and the trial matrix. ■If you selected file input, enter the name of the file containing the trial matrix. |
DOE Technique | (Appears only if you selected Built-in DOE Technique above) Select a DOE technique. ■Full Factorial ■User Defined Algorithm 1 ■User Defined Algorithm 2 ■User Defined Algorithm 3 The DOE technique or trial matrix controls the number of simulations and the combination of variable values to use for each simulation. For example, the Full Factorial technique simulates every possible combination of levels. If you use two variables with three levels each, Adams View runs nine simulations. User Defined Algorithm 1/2/3 will invoke a user-written optimization algorithm that has been linked to Adams View. For more information on how to do this, see Linking External Algorithms. The DOE technique or trial matrix selects values for a variable based on the range or list of values you defined for the variable. ■If you specified only a range for a design variable, Adams View selects from equally spaced values across the range. You enter the number of values in the Default Levels text box. ■If you specified a list of values for a design variable, Adams View selects directly from those values, ignoring the value in the Default Levels text box. |
Check Variables Guess # of Runs. | (Appears only if you selected Full Factorial as the DOE Technique above) Select if you want to check that the variables have the same number of levels and display the required number of runs. |
Number of Trials | (Appears only if you selected Direct Input for Trials Defined by) Enter the number of trials (simulations) and the trial matrix. |
Trial Matrix File | (Appears only if you selected File Input for Trials Defined by) Enter the name of the file containing the trial matrix. |
Edit Trial Matrix File | (Appears only if you selected File Input for Trials Defined by) Select to edit the trial matrix file. |
Preview | Shows you each configuration of your model for every design variable. Displays an alert box asking you if you want to pause after each configuration. Select YES to pause. |
Start | Begins the simulation. Adams View runs a simulation for each trial that the DOE technique or trial matrix defines. When the simulations are done, Adams View returns the variables to their original values. |
Optimization | |
Design Variables | Enter the name of the design variables to vary. ■If you specified value ranges on any of the design variables, Adams View increases or decreases the objective as much as possible without exceeding the value limits. ■If you specified constraints, Adams View increases or decreases the objective as much as possible without violating the constraints. As Adams View runs the optimization, it iteratively adjusts the design variable values, attempting to improve the model performance with each iteration. Adams View may need to backtrack to avoid violating a constraint or limit on a variable value. Therefore, the model performance does not necessarily improve with each iteration. At each iteration, Adams View runs several simulations to approximate derivatives and converge on the next iteration. |
Auto. Save | Select if you want to automatically save the original values of the design variables before starting the optimization analysis. |
Goal | Select either Maximize or Minimize. If you select Maximize as the goal, Adams View adjusts the design variable values to increase the measure or objective as much as possible. If you select Minimize, Adams View reduces the objective as much as possible. |
Constraints | Select if you want to add constraints and then enter the names of the constraints in the text box that appears. |
Start | Begins the simulation. The last iteration will be the best values that the optimization could find without violating constraints or limits. Adams View normally leaves the design variables set to the optimized values. If you interrupt the analysis or Adams View encounters an error during the analysis, Adams View resets the variables to their original values. If you do not want to keep the optimized values, and you selected the Auto. Save check box or used the Save button to save the original values, you can select the Restore button to return the variables to their original values. |
Temporary Settings Sweep | |
Temporary Settings Sweep | Specify one or more Temporary Settings Files(.tsf) files. Property values contained in the file(s) will be applied before starting the simulations and then reverted to their original values immediately after the simulations finish, even if some of the simulations fail to complete. Note that this option menu available only if the Temporary Settings capability has been enabled from the AView-Preferences section of the Adams Registry Editor. ■Trial – Uneditable by users, these cells simply count the rows in the table ■Temporary Settings File – Cells which can be populated by one or more .tsf files browsed for via the same file browser as in other places in AView that already reference TSF today ■Insert – Inserts a row above the row you selected ■Remove – Removes the row you selected ■Start - Begins the simulation After you select Start, Adams View runs a simulation for each trial of the Temporary Settings File per trial row. In which, for each trial, the model will be updated as per temporary settings file(s) applied per trial and when the simulations are done, Adams View returns the model to its original state. Note: When using the Temporary Settings Sweep option, the "set variables to values used in trial or iteration" button is disabled because it is specific to setting a single set of variables used across all trials. The Temporary Settings Sweep option is richer, allowing one to perturb different properties per trial, this button does not apply. If you want to update your baseline model to the state used in a given Temporary Settings Sweep trial, use the Temporary Settings dialog to select the same set of temporary settings files and apply them to your model. |
The following buttons are available for all four types: | |
Display, Output, and Optimizer | Displays the Solver Settings dialog box for either display, output, or optimizer options. Note that each button brings up a different option in the Solver Settings Dialog Box. Note: The Adams Solver settings for the Optimizer will, of course, only influence and Optimization multi-run job |
