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 HyperMesh 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 HyperMesh 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. Figure 2.
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 HyperMesh.
Before you begin, load the OptiStruct user profile and open
the pbeaml.fem input file from
<installation_directory>\hwdesktop\tutorials\hm.
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, HyperMesh automatically creates beam sections which allow
you to visualize the sections in 3D.
Import pbeaml.fem into HyperMesh.
Turn on beam visualization.
From the View Controls toolbar, click .
Click the first icon in the microdialog to
display 3D or 1D & 3D beam sections.
