Selecting an Input File and Preparing the Component

To locate the parameters to be used in your Isight model, you need to select a PAM-CRASH input file and prepare the component using the PAM-CRASH Prepare Wizard.

  1. Double-click the PAM-CRASH component icon .

    The PAM-CRASH Component Editor appears.

  2. From the PAM-CRASH Component Editor, click the Input tab.

  3. Click Browse.

  4. Navigate to the PAM-CRASH model ( .pc ) file you want to use, and click Open.

  5. Click Ignore Non-Existent Included Files if the included files do not exist at the location specified in the PAM-CRASH input file.

  6. Click Read Input File.

    The PAM-CRASH Prepare Wizard appears.

  7. Set the options in the Component Setup dialog screen.

    The path and the name of the PAM-CRASH input file appear in the Input File field.

    1. Specify the Work Directory.

      The component saves the prepared files at the path in the Work Directory field. The default path is <Input File Directory>\Isight. For example, D:\PAM-CRASH\Isight, where D:\PAM-CRASH is the directory where the input file is present and Isight is the name of the subdirectory that the component creates to save the prepared files.

      You can enter a different path by clicking Browse.

    2. In the Subfolder for INCLU Files field, enter the name of the folder to be created inside the Work Directory to save the included files.

      The default folder name is INCLUDE; hence, the path where the include files are saved will be <Input File Directory>\Isight\INCLUDE. For example, D:\PAM-CRASH\Isight\INCLUDE.

      You can enter a different name in this field, and the component creates a folder with this name.

  8. Select the File Management option:

    Option Description
    Files Managed By User The component creates a folder for saving the include/supporting files. This option is recommended and is selected by default.

    The folder will be created with the name in the Subfolder for INCLU Files field.
    Files Managed By Isight The component does not create a folder to save the included/supporting files.

    This option is disabled if you select Ignore Non-Existent Included Files check box in the Input tab.

  9. Click Next.

    The component creates the work directory and the subdirectory to save the prepared files, and the Select Files to Divide dialog screen appears, which displays the input and the included files.

  10. Click the check box corresponding to the file that you want to divide.

    The size of the input file containing the FEM mesh data is usually large. It is recommended that you divide this file into two files (main and mesh) to improve the performance of the component.

    Note: If you have selected Ignore Non-Existent Included Files in the Input tab, the included file must not be divided.

  11. Click Next.

    The Divide Files dialog screen appears, which shows how the files selected from the Select Files to Divide dialog screen will be divided.

    The Divide Files dialog screen does not appear if you do not select any file from the Select Files to Divide dialog screen.

  12. Click Next.

    The component divides the selected files into two files (main and mesh). One file saves the FEM mesh data, and the other file saves the boundary condition data.

    The File Options dialog screen appears, which displays the files that were created after splitting the files selected from the Select Files to Divide dialog screen.

  13. From the File Options dialog screen, select the files that you do not want to modify. You cannot select the master file.

    Note: If you selected Ignore Non-Existent Included Files in the Input tab, you must specify which included files should be ignored.

    The paths of the selected files (as per the input file) are displayed in the File Path column.

    The files containing the mesh data are selected by default; it is recommended that you do not create file parameters for these files because they are large. If you try to clear their corresponding check boxes , the No Change Setting Warning dialog box appears. Click OK to close the dialog box.

  14. If desired, edit the path of the selected files. Then copy the file to the new location.

  15. Click Finish.

    The Summary dialog box appears, which displays the list of files and file parameters created and shows the list of files, their paths as per the input file, and the paths where they need to be copied, in case their paths were edited in the File Options dialog screen. In addition, the ignored non-existent files, if any, also appear.

  16. Click OK to close the Summary dialog box.

    The component editor is populated with the created files and the input and output parameters. The File List, Shell Thickness, Material Property, Contact, Sensor, Rupture, and Curve subtabs appear on the Input tab.

  17. In the File List subtab, view and confirm which files will be parsed and updated and which files will not be updated by the component.

    The files for which the corresponding option in the Parsing column is selected will be parsed and updated by the component, and the files for which the corresponding option in the No Change column is selected will not be updated by the component.
