Before Using This Command

  • You must have access to an existing PDS Piping model containing a completed pipeline.

Operating Sequence

  1. Select the PDS icon.

    The system displays the Plant Design System form.

  2. Select the Project Number.

    Select the PDS project from which the neutral file will be generated.

  3. Click Pipe Stress Analysis.

    The system displays the Plant Design - Stress Analysis form.

  4. Enter 3-D Model Number(s).

    Select a Model No field and key in a valid model number. Do not key in the .dgn filename.

    The software checks the model number for validity and either accepts the entry and moves the cursor to the next Model No field or displays an error message in the message field.

  5. Select the Pipeline Names field adjacent to the Model No field selected in the previous step and key in a valid pipeline name. See Pipeline Names for more information on defining a pipeline name or stress analysis number.

    The software accepts the entry and moves to the next Pipeline Names field.

  6. Select the Stress Output Node:Path field and key in the location of the neutral file.

    The Stress Output location should be in the format: nodename:drive:\users\stress.

    A default setting can be set for Stress Output by exporting the following statement in the pds.cmd file.

    $ENV{'STRESSPATH'} = 'nodename:drive:\users\stress';

  7. Select Stress Options File field and key in the location of the options file.

    • The Stress Options File location should be in the format: nodename:drive:\users\stress\defaults.dat.

    • If any setting of the Stress Options File is changed after the completion of a previous run or before selecting Accept for the next run, the changed setting is recognized by pressing Enter in the Stress Options File input field.

    • A default setting can be set for Stress Options File by exporting the following statement in the pds.cmd file.

      $ENV{'STRESSOPTION'} = 'nodename:drive:\users\stress\defaults.dat';

  8. Select the Confirm button to accept the data displayed on the form and begin generating the neutral file.

    The system displays the message:

    Creating Neutral File

    When the neutral file generation is completed, the system displays a status form.

    The status form displays any processing information, warning messages and/or error messages that occur during the generating process. Use the scroll bar and buttons to scroll through the information displayed on the status screen. Refer to the section Warning and Error Messages for detailed descriptions of each warning and error message.
