HyperWorksEngineering Solutions is a modeling and visualization environment for NVH, Crash, CFD, Drop Test 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.
The Drop Test Manager is an automated solution that allows you to either simulate a single drop test or a choice of
multiple iterations with the aim of finding the sensitivity of process variables like initial orientation and drop
height in a typical drop test by controlling the run parameters and conditions with ease.
Many essential utility tools using HyperWorks-Tcl have been developed over the years to support Aerospace customers. A few tools have been collected and upgraded to
be compatible with this release.
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.
The Domains and Handles approach involves dividing the mesh into domains containing elements or nodes and placing
handles at the corners of those domains.
Each global domain is associated with any number of global handles. Global handles will only influence the nodes contained
within their associated global domains. Global domains and handles are best for making large scale shape changes to the
model.
Each local domain is associated with any number of local handles. Local handles will only influence nodes contained within
their associated local domains. Local handles are intended to be used to make small scale, parametric changes to the model.
Partitioning is a method of dividing 2D domains into smaller 2D domains at logical places, such as at the edges of surfaces
associated with the mesh, or where the angle between elements exceeds a certain value, or where the domain changes from
flat to curved.
Space frames are models that have a sparse distribution of elements, such as a car body. Space frame models can generally
have element counts in the hundreds of thousands, but their basic structure is rather simple.
Shell models are models that are made up primarily of shell elements, namely, quads, and trias. In general, a shell
model represents many parts, each with numerous features such as holes and edges, and connected together using 1D
elements such as bars and rigids.
Solid models are models that are made up of solid elements, namely, tetras, pentas, and hexas. In general, a solid
model represents a single part with numerous features such as holes, edges, bosses, flanges and ribs.

handles are best for making large scale shape changes to the model.
Global domains are represented by a cube made up of dashed lines, and located at the
centroid of the nodes which make up the global domain.
Global handles are the largest handles in the model. Handles are colored red if they are
not dependent on other handles, and they are colored yellow, cyan, or violet if they are
dependent on other handles. The handle color indicates their level of dependency. Dependent
global handles are also smaller than the handles on which they are dependent. The base size
of all the handles in the model can be set on the morphing Visualization Controls tab
accessed by using the Visualization options () on the Visualization toolbar. The
size given is used as the radius for the independent global handles. You cannot edit the
color of the handles nor the relative size between the dependent and independent handles.
However, you can edit the color of the domains in the morphing Visualization Controls
tab.
The Domains panel is used to create, edit, and organize global domains. When a global
domain is created with the create handles option selected, HyperMorph generates several global handles. Global handles are
generated at each of the eight corners of a box surrounding the model laid out along the
global axes. These global handles are named corner followed by a number from one to eight.
HyperMorph also places at least one global handle within the
global domain box in areas of peak nodal density within the model. HyperMorph generally creates no more than about 30 global handles
within the global domain box. These handles are named global followed by a number. The
automatic global handle generation works well for space frame models such as full car
models. If the handles are not generated in the positions where you want them to be, you can
always delete them, reposition them, or create new handles using the Handles panel.
The method for determining how global handles associated with global domains influence the
mesh can be selected in the Morph Options panel, Global subpanel.
Hierarchical
Global handles influence the local handles found at nodes inside the global domain,
which in turn influence nodes within the local domains.
Direct (default)
Global handles influence the nodes in the model directly even if the nodes are not
in a local domain.
Mixed
Global handles will influence every node inside the global domain using the
hierarchical method if the node is inside a local domain, or the direct method if the
node is not in a local domain.
There are subtle differences in how the global handles influence the nodes for each
method with the main difference being that the parts of the model defined by local edge
domains have their shape preserved when using the hierarchical method. Straight edges will
remain straight and circular holes will remain circular for the hierarchical method, while
the direct method may bend or warp these features into curved edges and elliptical holes.
You should select which method is right for the type of morphing that you want to perform.
If you wish to preserve the local geometry, choose the hierarchical or mixed method. If you
are willing to accept distortions in the local geometry, choose the direct method.
The influences between the global handles and local handles using the hierarchical method
or nodes using the direct method can be calculated using either the spatial method or the
geometric method. Both methods attempt to determine how a global handle affects nodes or
local handles in the space surrounding it. The spatial method is the default, and is the
fastest and most robust method for generating global influences based on a spatial
formulation for the entire model. The geometric method can be slow for large models or large
numbers of global handles, but may produce more desirable influences. The geometric method
is the method that was originally used in HyperMesh and
generates influences based on the geometric relationship between a given node or local
handle and the surrounding global handles. The method used can be selected in the global
subpanel of the Morph Options panel.
