The recommended workflow for using the Buried Pipe Modeler is outlined in the steps below.

A buried pipe example problem is provided to illustrate the features of the modeler. This example should not be considered a guide for recommended underground piping design. For more information, see Buried Pipe Example.

  1. Click Underground Pipe Modeler on the CAESAR II toolbar or click Input > Underground to open the modeler.

  2. Click File > Open on the Buried Pipe Modeler main menu and select the original unburied job.

    The original job serves as the basis for the buried pipe model. It must already exist and need only contain the basic geometry of the piping system. The modeler will remove any existing restraints in the buried portion.

  3. Click Soil Models on the Buried Pipe Modeler toolbar.

  4. In the Basic Soil Modeler dialog box, select a Soil Model Type.

    The software populates the dialog box with soil data properties specific to the soil model you select.

  5. Enter the necessary soil data and click OK to exit the dialog box.

    SHARED Tip To enter additional soil models, click Add New Soil Model.

    The software saves the soil data in a file with the extension SOI.

  6. In columns 1-5 of the buried element data input area, describe the sections of the piping system that are buried and define any required fine mesh areas and click Save .

    SHARED Tip User-defined soil data can be entered in columns 6-13.

  7. On the Buried Pipe Modeler toolbar, click Convert to convert the original model into the buried model. This step produces a detailed description of the conversion.

    By default, the software appends the name of the job with the letter B. For example, if the original job is named UndergroundPipe, the software saves the second input file with the name UndergroundPipe B. If the default name is not appropriate, click File > Change Buried Pipe Job Name and rename the buried job.

  8. Click File > Exit to return the CAESAR II main window. From here, you can use Input > Piping to review and edit the buried model, add any additional underground restraints (such as thrust block) to the buried model, and perform the analysis of the buried pipe job.
