FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry
is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
1D mesh that allows accurate testing of connectors, such as bolts, and similar rod-like or bar-like objects that can
be modeled as a simple line for FEA purposes.
Volume mesh or "solid meshing" uses three-dimensional elements to represent fully 3D objects, such as solid parts
or sheets of material that have enough thickness and surface variety that solid meshing makes more sense than 2D shell
meshing.
1D mesh that allows accurate testing of connectors, such as bolts, and similar rod-like or bar-like objects that can
be modeled as a simple line for FEA purposes.
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.
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.
Use a text editor to inspect the following file:
pbeaml.fem.
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.
Import pbeaml.fem into HyperWorks.
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.
