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.
Smooth Particle Hydrodynamics (SPH), Finite Point Method (FPM) is a technique used to analyze bodies that do not have
high cohesive forces among themselves and undergo large deformation, such as liquids and gases.
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.
Produce an all-hexa or all-tetra mesh based on the selected elements or geometry, then use the shrink wrap functionality
as a quick mechanism to generate solid meshes.
Acoustic Cavity meshing generates a fluid volume mesh used to calculate the acoustic modes (or standing waves) inside
the air spaces of a vehicle or similarly enclosed structural model.
Gasket elements are used to model components with a very thin thickness, with their main purpose being to act as a
sealing between structural components.
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.

Note: When generating such a mesh, the Jacobian value has a large effect on the
coarseness of the resulting volume mesh, as described below.
Using the shrink
wrap mesh to achieve improved FE output from OptiStruct
topology runs has also provided very good results which allow for quick tetra-meshing
and, therefore, quick re-analysis after the optimization run.
Comparison of Altering the Jacobian Value for Solid Mesh Generation
Within both tight and loose wrap algorithm’s there is an option to generate solid
mesh. This will generate an all hexa mesh on completion of the shrink wrap. When the
generate solid mesh checkbox is selected it will expose a
minimum jacobian input, this option essentially will hexa mesh the part with this
element quality criteria defined, it controls the hexa quality which is directly
linked to the adherence to the topological features of the original component. The
jacobian value must be between 0 and 1. The nearer the value is to 1 the cruder the
output will appear, the mesh will be more heavily voxelised. When the value is
closer to 0, you are allowing the shrink wrap solid mesh algorithm to smooth and
adhere to more features while maintaining the solid mesh minimum jacobian element
quality. By default the minimum jacobian value is 0.3.
