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.
OSSmooth is a semi-automated design interpretation software, facilitating the recovery of a modified geometry resulting
from a structural optimization, for further use in the design process and FEA reanalysis.
Topology optimization results are interpreted to provide an iso-density surface based on the volumetric density information
of a topology optimization, which is conducted using OptiStruct.
FEA topology for reanalysis provides an iso-density surface based on the volumetric density information from a topology
optimization. Through tetrameshing for 3D models and inheriting boundary conditions, the results from FEA topology can
be used for quick reanalysis.
The FEA topography option in OSSmooth allows the results from an OptiStruct topography optimization to be interpreted as one or two level beads and recover boundary conditions upon geometry extraction.
An option for iso surface is also provided for combined use, which performs the same functionality as FEA topology, with
FEA topography.

Laplacian smoothing can be used in the smoothing of the results of topology
optimization.
The laplacian_smoothing statement controls the iteration number of
when the Laplacian smoothing will be performed and the feature angle threshold to preserve
normal discontinuity at corners.
Laplacian smoothing creates smooth boundary iso-surface by entering 1 as the 3rd argument
of the laplacian_smoothing parameter statement. Comparing Figure 2 and
Figure 3,
notice that Figure 3 is almost ready for casting.
The advantages of the laplacian_smoothing statement in OSSmooth
include:
The flexibility of controlling the number of smoothing iterations to obtain different
degrees of smoothing (possibly a smoothing quality ready for casting). Normally, the
iteration number ranges from 5 to 20.
Smooth boundary of iso-surface with feature angle constrain are seamlessly
incorporated into the smoothing process, which is more challenging in a pure CAD
system.
