Import/Export HyperBeam Comments

Overview of how to import and export HyperBeam comments.

  • Import HyperBeam comments.

    On import of an FEA model, beamsections are automatically created for all bar, beam, and rod properties that do not already have beamsections defined. These beam sections automatically populate bar, beam, and rod property cards and the cross-section should be edited with HyperBeam. 3D visualization of beams in HyperWorks is only made possible through HyperBeam beamsections and their association to properties.

    To import a FEA model without automatically creating beamsections for each 1D property, use the custom import feature with beamsections and beamsection collectors unchecked. The section information on the actual property cards will remain intact, but the geometric and section calculation data will be missing.

    Figure 1.
  • Export HyperBeam comments.
    Exporting an FEA deck in HyperWorks operates in a similar fashion. HyperBeam comments are written out by default (as are all HyperMesh comments). In order to suppress HyperBeam comments from being exported, you must use the Custom export feature to turn off all comments. Beamsections are stored as HyperBeam comments in an exported deck.

Example: Import and Automatic Beamsection Creation

This example illustrates the automatic creation of beam sections on import and the visualization of these rods, bars, and beams in HyperWorks.

Before you begin, load the OptiStruct user profile and open the pbeaml.fem input file from <installation_directory>\hwdesktop\tutorials\hm.
  1. Use a text editor to inspect the following file: pbeaml.fem.

    Figure 3.
    There are no beam sections or HyperBeam comments defined in this input file. When imported, HyperWorks automatically creates beam sections which allow you to visualize the sections in 3D.
  2. Import pbeaml.fem into HyperWorks.
  3. Turn on beam visualization.
    1. From the View Controls toolbar, click .
    2. Click the first icon in the microdialog to display 3D or 1D & 3D beam sections.
