Engineering Solutions is a modeling and visualization environment for NVH, Squeak and Rattle Director, Crash, CFD, and Aerospace using
best-in-class solver technology.
The Crash application offers a tailored environment in HyperWorks that efficiently steers the Crash CAE specialist in CAE model building, starting from CAD geometry and finishing with
a runnable solver deck in Radioss, LS-DYNA and PAM-CRASH 2G.
HyperWorks offers high quality tools for CFD applications enabling the engineer to perform modeling, optimization and post-processing
tasks efficiently.
Collectors are named organizational containers for collected entities. Collected entities are nameless entities which must
reside within one, and only one, collector. Collected entities are mutually exclusive to a collector.
Ale Fsi Projection entities provide a coupling method for simulating the interaction between a Lagrangian material
set (structure) and ALE material set (fluid).
Ale Reference System Curve entities defines a motion and/or a deformation prescribed for a geometric entity, where
a geometric entity may be any part, part set, node set, or segment set.
Ale Reference System Switch entities allows for the time-dependent switches between different types of reference systems,
that is, switching to multiple PRTYPEs at different times during the simulation.
Ale Tank Test keyword provides curve through an engineering approximation when control volume airbags only require
two engineering curves to define gas inflator and those two curves can be experimentally measured but the ALE inflator
needs one additional state variable - the inlet gas velocity which is impractical to obtain.
In LS-DYNA, damping entities define damping applied on the parts and nodes in case of *DAMPING_GLOBAL. In Radioss, damping entities used to set Rayleigh mass and stiffness damping coefficients are applied to a set of nodes
used to stabilize the results.
When source data is not in the correct location and overlaps with the target model, the tools provided in the Field Realization dialog can be used to transform the source model to the target model's location with linear transformation,
rotation, or scale methods.
Joint entities define the kinematic relationship between two bodies (for Ball, Cylinder, Revolute, Slider joints) or three
bodies (for DoubleSlider joints).
Region entities store information used to facilitate and automate modeling practices and processes. It enables a selection
which can be common across design changes or other models, provided region data is the same.
Rigid wall entities provide a method for treating a contact between a rigid surface and nodal points of a deformable body.
In the LS-DYNA and Radioss user profiles, rigid walls can be created in the Model and Solver browsers.
State Equations are used to describe the thermodynamic equation relating material state variables under a given set
of physical conditions, such as pressure, volume, temperature, or internal energy. State Equations are useful in describing
the properties of fluids, mixtures of fluids, and so on.
Transformation entities define solver transformations, and are used to define a transformation sequence in a Position
entity, to be applied on a set of nodes or on a SolverSubmodel.
Browsers supply a great deal of view-related functionality in Engineering Solutions 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.
Perform automatic checks on CAD models, and identify potential issues with geometry that may slow down the meshing
process using the Verification and Comparison tools.
Perform nodal force balance mapping using OptiStruct to
ensure mapped target nodal forces and source nodal forces are in equilibrium.
Forces from a source model are mapped to new target model nodal forces. The total
load calculation on the source model and the new mapped model must be the same in order
to ensure forces are balanced.
Equilibrium mapping is performed using the linear
OptiStruct solver, therefore you must have the
OptiStruct installed with license on the same
installation directory as HyperWorks Desktop.
Open or import the target model. When importing, use ID Offset to preserve the
source model ID.

New forces and moments are created and applied to the nodes of
the target mesh. Figure 4.
