Setting the Execution Options

You can use the Execution tab to control execution options including the Nastran command line, the component time out, and whether to wait for the output file before continuing. You can also specify the configuration file, as well as how to handle Nastran INCLUDE statements when parsing the input file.

  1. Double-click the Nastran component icon .

    The Nastran Component Editor appears.

  2. From the Nastran Component Editor, click the Execution tab

  3. Configure the Runtime Options.

    1. Accept the default command line, or click Browse to specify a different command line.

      The default command line is nastran <bdf_file>. For example, nastran carbody.bdf, where carbody.bdf is the input file name.

    2. In the Time Out field, enter a value (in seconds) to specify how long to wait for execution before determining that execution failed.

      The default value is 300 seconds.

    3. Select Wait for output file if you want the component to wait for a specified amount of time for the Nastran output file to become available. You should use this option if you are executing the component in a queuing system.

      In the Max Wait field, enter the time that the component will wait for the output file to become available. In the Additional Wait field, enter the additional time to be allotted to finish the file transfer after the output file is available.

      The default Max Wait time is 30 seconds, and the default Additional Wait time is 0 seconds.

  4. Configure the Designtime Options.

    1. Specify the Config File.

      The Nastran configuration file allows you to configure the parameters that the component extracts from the Nastran input and output files. The default path for Nastran configuration file is <Isight_install_directory>\<operating_system>\reffiles\SMAFIPconfig\MSCNastran\NCConfig.txt.

      Click Browse to locate a different configuration file.

    2. Select one of the following Include Options:

      Prompt before parsing an include file Prompt you whenever an INCLUDE statement is found during parsing.
      Parse all include files Parse all the include files.
      Do not parse include files Do not parse the include files.
      The Nastran component provides support for Nastran INCLUDE statements in the input deck. File parameters are created for all INCLUDE files; however, you can set whether INCLUDE files should be parsed for parameters or not.

      Note: All included files must exist in the same directory, and the INCLUDE command must use a relative path. For example,

      Valid:
      INCLUDE	Grid.bdf
      Invalid:
      INCLUDE	C:\data\Grid.bdf

  5. In the Log Output area, set the logging options.

    1. Select Log Standard Error if you want the messages that Nastran writes to standard error to appear in the Logs tab on the Isight Runtime Gateway.
    2. Select Log Standard Output if you want the messages that Nastran writes to standard output to appear in the Logs tab on the Isight Runtime Gateway.
    3. In the Log at most field, specify the limit for the number of lines to be logged.

      Only the number of lines specified will be displayed in the Logs tab on the Isight Runtime Gateway. Half of the lines are taken from the start of the execution process, and half are taken from the current or from the end of the process. Lines from between the two are discarded.

      The default value is 21 lines.

  6. Click OK to save your changes and to return to the Design Gateway.
