Create and Edit a Pipe

A pipe is a one-dimensional structural element with a constant cross-section that supports bending, torsional, longitudinal, and higher-order, cross-sectional deformation modes.

  1. From the Model ribbon, click the Structural > Pipe tool.
    Figure 1.


  2. Create a pipe.
    1. Left-click in the modeling window to select a point or node until you are able to create a pipe.
    2. After selecting more than two points, a guidebar is displayed that you can use to assign properties, , and damping, .

    3. Specify the name in the field.
    4. Click and assign properties and damping, respectively.
    5. Click Create to create a pipe.
      Figure 5.


      The required parameters to create the pipe subsystem are updated.

  3. Right-click on pipe to edit the subsystem and update the parameters.

    Name
    Specify unique name.
    ID
    Specify unique ID.
    Config
    Specify the element type.
    Property
    Specify the property parameter based on the element type.
    Damping
    Specify damping to the subsystem.
    Geometry
    Based on the element type, update the geometry parameters.
    Generally, the geometry is automatically updated from the user-defined geometry. You can modify the geometry information by clicking User Defined as shown below.

    Subsystem Options
    For experienced users, expand the Subsystem Options to change the default choices for the SEA Subsystems for all element types. For certain structural element types, use these options to adjust the default bending stiffness or conductance of the element and add non-structural mass, component mass, or fluid loading to the element when the options have been changed.
    Damping
    Assign a damping model to the element. From the Damping field drop-down menu, select a damping model. This list contains all predefined models which apply to the current element type. Click to display advanced damping options that you can use to define additional damping models.
    Properties
    Assign a property model to the element. From the Property field drop-down menu, select a property model. The element materials and cross-sectional parameters defined in the selected Property record are displayed. Property records can be used to simplify the model definition in cases where many elements have the same properties. Click to display advanced property options that you can use to define additional property models.
