Importing a Parse from a Description File

A description file (.desc) uses iSIGHT’s Multi-Disciplinary Optimization Language (MDOL) to build a design. Within these files are segments of File Description Command (FDC) code. When you select a description file, the names of the parses and their contents are imported into Isight. Using a description file from iSIGHT, you can select a set of FDC instructions. Isight attempts to populate the additional information automatically.

Note: You must declare arrays at the beginning of the File Description Command (FDC) using the require statement. Otherwise, Isight treats arrays as scalar parameters within the simulation process flow.

  1. Double-click the iSIGHT File Parser component icon .

    The iSIGHT File Parser Component Wizard appears.

  2. Select Use an existing FDC located in an iSIGHT description file, and click Next.

    The Select a description file screen appears.

  3. Click Browse to locate the description file that contains the parse, and click Open.

    Information about the description file appears in the File Details area.

  4. Click Next.

    The Select a FDC from the list below screen appears.

    Within description files are segments where entire parses are defined. After you select a description file, the names of the parses within the description file and their contents appear in the iSIGHT File Parser Component Editor.

  5. In the Available FDCs area, click the parse that you want to use.

    Information about the parse appears in the FDC Contents and Additional Information areas. The wizard attempts to determine all the necessary parameters. Verify that all parameters are listed.

  6. Click Finish to exit the wizard and to return to the iSIGHT File Parser Component Editor.

  7. Click the button to view the parse.

    • If you are performing an input parse and all the necessary information is available (e.g., FDC file, template, parameters with desired values, etc.), you can view how the parsed file will appear on the Produced tab. If a produced file is not specified, you can still view the parse; however, you are warned that you need to specify the file before execution.

    • If you are performing an output parse and all the necessary information is available (e.g., the output file is populated with the desired values/info, FDC file, and the parameters that you expect to get back from the parse), clicking enters the values of the parameter table.

  8. Update the parameter information on the right side of the editor by either adding new parameters, deleting existing parameters, or adding new members to aggregate parameters.

    You can sort the parameter information by clicking the column headings.

    For more information about parameters, see Working with Parameters and File Parameters in the Isight User’s Guide.

  9. If desired, change the parse information.

    • For input parses, change the parse information directly in the File Contents area of the Template and Input FDC tabs, as desired.

    • For output parses, change the parse information directly in the Output and Output FDC tabs.
