Configuring the Data File Sampling Method

You can create an approximation using the Data File sampling method, where Isight uses an existing file that contains data points.

  1. From the Sampling Options screen or the Error Analysis Sampling Options screen, click Browse to locate the file that you want to use.

    The Select File dialog box appears.

  2. Locate the file, and click Select.

    The file name appears in the text box.

  3. Specify the type of file you selected:

    • Static file. Select this option if the data in the file never changes. The file will be read once and saved in memory for future use.

      Note: If you later access the Approximation Wizard to view the approximation you are creating, the Re-read File option is activated. Clicking Re-read File allows the wizard to scan the file for changes since it was first read and placed into memory.

    • Dynamic file. Select this option if the data in the file can change. The file will be read prior to every initialization. If you are executing the model on a SIMULIA Execution Engine, the file must be accessible through the absolute path or shared file system. For more information, see Creating a SIMULIA Execution Engine Connection Profile.

    • File parameter. Select this option to force Isight to create a preconfigured file parameter named Initialization Data for <Approx_Name> in the component. You can map this file parameter to receive data from another component at run time. The approximation uses this data for initialization.
