Creating 1D Properties

You can create a 1D structural property and apply it to a meshed support. Applying a 1D property to 1D elements allows you to specify the physical behavior of the 1D elements.

Important: The availability of some of the 1D property parameters depends on your available licenses. See Licensing.

Before you begin: An ELFINI linear elastic material must be applied. See Applying a Core Material.

  1. In the Structural Properties toolbar, click 1D Property .

    The 1D Property dialog box appears.

  2. Optional: In the Name box, modify the name of the property.

  3. Select a 1D body or a 1D beam mesh to be applied a 1D property.

    The 1D Property dialog box is updated. The material that has been applied to the selected support appears automatically in the Material box, and the domain that will be used is displayed automatically in the Domain box. By default, the first domain or the domain that has been set as default is selected (see Setting a Default Material Domain).

    Warning: Only isotropic materials are allowed in the 1D property definition. See ELFINI Linear Elastic Material Properties.

  4. Optional: Choose another ELFINI linear elastic domain.

    1. Click .

      An immersive window appears and displays all the domains associated to the selected material.

    2. Double-click the domain you want to use.

    The immersive box closes and the selected domain is displayed in the Domain box.

  5. In the Type list, select the type of beam section you want.

    To learn more about the beam section types, see 1D Property Section Types.

  6. Click to define the beam section parameters.

    The Beam Definition dialog box appears. To learn more about the section characteristics, see 1D Property Section Types.

  7. In the Beam Definition dialog box, select one of the following:

    • Constant to create a constant beam section.
    • Variable to create a variable beam section.
      Important: This option is not available if you selected Rod or Beam from surface in the Type list of the 1D Property dialog box.

  8. Enter the beam section characteristics.

    See 1D Property Section Types.

  9. Click Close in the Beam Definition dialog box.

  10. Optional: Select the Orientation geometry box to activate it, and select a point, a line, or a face to orient the beam section.

    See Beam Section Orientation.

  11. Optional: In the Offset list, select Customized to define an offset value, and click to define the offset values.

    Warning: You cannot define an offset value if you selected the Rod type.

  12. Optional: In the DOF released list, select Customized to release or impose degrees of freedom, and click to specify the degrees of freedom that you want to release.

    Warning: You cannot release the degrees of freedom if you selected the Rod type.

  13. Click OK.

    The 1D property is created.
