Configuring the Technique and Execution Options

You use the General tab to select the technique and set any tuning parameters associated with the technique. In addition, you can also set options that you want the component to take during execution.

Note: If you are connected to a SIMULIA Execution Engine and a message appears about some optimization techniques not being published, you need to publish the techniques to the SIMULIA Execution Engine Library if you plan on using the available techniques.

Execute the publishall file, from a command prompt or terminal window, located in the following directory:

<Isight_install_directory>/<operating_system>/code/command/

You need to have SIMULIA Execution Engine administrator privileges to execute this file. When prompted, connect to the SIMULIA Execution Engine you are currently using with Isight and the optimization techniques are published. You will have to close and re-open the Optimization component before using these newly added techniques.

For more information about publishing to a SIMULIA Execution Engine Library, see the SIMULIA Execution Engine Installation and Configuration Guide that matches your installation or contact your local SIMULIA Execution Engine administrator.

  1. Double-click the Optimization component icon .

    The Optimization Component Editor appears.

  2. From the Optimization Component Editor, click the General tab.

  3. In the Optimization Technique list, select the technique of your choice.

    Information about the technique appears in the Optimization Technique Description area on the right side of the editor.

    For more information, see About the Optimization Techniques.

  4. If desired, review the information in the Optimization Technique Description area.

    For additional information on the technique, see About the Optimization Techniques.

  5. In the Execution Options area, set the following, if available:

    Option Description
    Execute in parallel Click this option to execute design points in parallel, small batches. The size of the batch depends on the number of selected design variables for numeric techniques or the size of the population for exploratory techniques.
    Restore optimum design point after execution Click this option to set parameters to the best design point after execution. If this option is not selected, the optimization keeps all parameters at their last values (last execution of the subflow) after execution.
    Re-execute optimum design point Click this option to force the optimization component to re-execute the optimum design point after the optimization ends. Re-executing is recommended if there are some output parameters that are not directly involved in optimization, but their values depend on the values of design variables (e.g., output file parameters).
    Use automatic variable scaling Click this option to scale design variables using their respective ranges (i.e., distances between their upper and lower bounds). Isight removes the Scale Factor column from the Variables tab because the scale factor values are calculated automatically.

    Note: You must define all upper and lower bounds (or allowed values) for all design variables when this option is selected. If some design variables do not have bounds, you will not be able to use this option.

  6. Set any Advanced Options. Advanced options include options that you want Isight to take after execution and termination criteria.

    For more information, see Configuring the Execution and Termination Criteria.

  7. Click the button to import all or part of the Optimization component configuration from a file or to export the entire configuration to a file.

    This provides you with an easy mechanism for quickly configuring the component using information that comes from an external source without manually entering all the information in the component editor. For more information, see About Importing and Exporting Configuration Files.

  8. If desired, map an option to a parameter.

    For more information, see Mapping Options and Attributes to Parameters.

  9. Click OK to save your changes and to close the Optimization Component Editor.
