Setting the Execution Options

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

  1. Double-click the NEiNastran component icon .
    The NEiNastran Component Editor appears.
  2. From the NEiNastran Component Editor, click the Execute tab.
  3. Configure the Runtime Options.
    1. Define the command line.

      The default command line is nastran <Input file>. For example, nastran knuckle.NAS, where knuckle.NAS is the input file name.

      Click Browse to specify a different command line.

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

  4. Configure the Designtime Options.
    1. Specify the Config File.

      The NEiNastran configuration file allows you to configure the parameters that the component extracts from the NEiNastran input and output files. The default path for the NEiNastran configuration file is <Isight_install_directory>\<operating_system>\reffiles\SMAFIPconfig\NEiNastran\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 filesParse all the include files.
      Do not parse include filesDo not parse the include files.
      The NEiNastran component provides support for Nastran INCLUDE statements in the input file. 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 NEiNastran 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 NEiNastran 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 by this option 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.
