Section Library

Use the automotive section library for rapid concept development in the early phases of the vehicle design process.

The automotive focused section library promotes rapid creation of full vehicle architecture concept models. The library consists of various sections from the 2011 Honda Accord Body in White (BiW) model. *
Note: You should be familiar with the Part Browser before using the section library.

To access the library:

  1. From the Assembly ribbon, click Libraries.
    Figure 3.

    Alternatively, in the Part Browser, right-click and select Library > Libraries....
    The Library Manager opens.
  2. Click to add a library.
  3. Set the library type to Part.
  4. Set the library template to Sections.
  5. Click to define the library path.
  6. Click Add then Connect.
    When Add is clicked, it automatically extracts the file found at <Altair>\hwdesktop\demos\hm\examples\libraryTemplates\part_library\ to the user-defined path.
  7. To access the contents of the library, load from the newly created library path defined in step 6.
    The .hm contains the file hierarchy library structure.

Sample Section

Each section in the section library contains:

  • A Beam element with a section property
  • 2D elements showing the shape of the section. The 2D element section is welded at the flanges.
  • Geometric lines representing the shape of the section that can be used for concept modeling. The geometric sections are not auto-welded at the flanges.
Figure 4. Sample Section

Although the geometric section lines are not welded, beam sections are auto-welded.

Numbering Scheme

The section library follows a numbering scheme that is explained in detail below.

Note: The numbering scheme is not mandatory and you can implement any numbering scheme of your choice.

Each section can be identified by a 7-digit number

  • The first digit from the left corresponds to the section’s location. It can take values of 1, 2, or 3.
    • 1: If the section is on the left side of the vehicle (for example, left-side B pillar)
    • 2: If the section is on the right side of the vehicle (for example, right-side B pillar)
    • 3: If the section is in the middle of the vehicle (for example, tunnel)
  • The second digit from the left corresponds to the assembly of the section. It can take values from 1 to 5.
    • 1: If the section belongs to the Side Frame assembly
    • 2: If the section belongs to the Roof assembly
    • 3: If the section belongs to the Front Structure assembly
    • 4: If the section belongs to the Front Floor assembly
    • 5: If the section belongs to the Rear Floor assembly
Figure 6. Second Digit Representing Different Assemblies

  • The third and fourth digits correspond to parts from the assembly. Each assembly has a number of parts; for example, the list of sample parts goes to 11 in Figure 8.
  • The fifth digit corresponds to the FE representation of the section. It can take values of 0, 2, or 5.
    • 0: If the FE representation is PBEAM
    • 2: If the FE representation is Beam Section
    • 5: If the FE representation is PSHELL
  • The sixth and seventh digits correspond to the component number.

An example of the numbering scheme implemented on the left-hand side rocker/sill section can be seen in Figure 7
