Browsers supply a great deal of view-related functionality by listing the parts of a model in a tabular and/or tree-based
format, and providing controls inside the table that allow you to alter the display of model parts.
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.
Tools and workflows that are dedicated to rapidly creating new parts for specific use cases, or amending existing
parts. The current capabilities are focused on stiffening parts.
Use the IP Impact tools to automatically calculate the instrument panel (IP) testing area according to the regulations
FMVSS201 and ECE-R21, position the headform impactor, and export ready-to-run solver decks for all the selected impact
locations.
The Pedestrian Impact tool automates the vehicle marking, impactors positioning and the export of solver decks with minimal
input, therefore reducing the full process lead time.
Use the Barrier Positioner tool to automatically get the impact barrier into
position, based on the selected crash regulation.
The barrier model must be defined in an
include file.
The solver transformation cards are automatically created to move the barrier at the
position corresponding to the selected protocol.
The Barrier Positioner tool supports the regulations: Roof Crush, C-NCAP, Euro-NCAP,
FMVSS, IIHS, J-NCAP and UN-R for frontal, side and rear load cases.
Restriction: Only available in the LS-DYNA and
Radioss solvers.
From the Safety ribbon, click the Barrier
Positioner tool.
On the guide bar, click to select the regulation, load
case and barrier position options.
Load Case: Select Front,
Side, Rear, or
Roof Crush.
Regulation: Select the regulation for the
selected load case.
Barrier Front Foam Distance: The search distance,
from the barrier frontal face, used to automatically identify the barrier
foam blocks.
Vehicle Front Axis: The orientation of the
vehicle.
Barrier Front Axis: The initial orientation of
the barrier.
Overlap (in % age): The lateral overlap between
barrier and vehicle for frontal and rear impacts.
Lateral angle: The rotation angle of the barrier
for frontal OMDB.
IRD/R-Point offset distance: The IRD or offset
distance to use for the positioning for side impacts. When the value is
equal to 0.0, the IRD or offset distance is automatically computed as per
the regulation.
Barrier Height From Ground: The height of the
barrier frontal zone above the ground, as per the regulation.
Vehicle To Barrier Distance: The offset between
the vehicle and the barrier.
Select the barrier components.
It is recommended to use the advanced selections ()
and filter “by include” and directly select the barrier include file.
Once
the barrier components are selected, all of the other displaced components
are automatically selected as vehicle components.
Once vehicle
components are identified, a microdialog
opens.
Select the relevant inputs needed for the selected regulation in the microdialog.
For example, for Euro-NCAP Side Impact, the following microdialog opens, where selections for Base Node and
Inclination Node define the ground position, and RPoint is provided.
Click Position.
The transformations to be applied on the barrier component are
calculated. The positioning process ends with the creation of the
transformations and position entity, as well as the update of the barrier
include file to an INCLUDE_TRANSFORM or SUBMODEL, respectively, for LS-DYNA and Radioss
solvers.
