Altair® OptiStruct® 7.0
Design, Analysis, Optimization
Altair OptiStruct is a highly advanced finite element based software
for both structural analysis and design optimization. OptiStruct is
used to design, evaluate and improve performance of mechanical
structures. Unlike classical finite element solvers, OptiStruct
software proposes new and better solutions throughout the entire design
process. Powerful optimization routines are deeply integrated with
popular analysis types including linear statics, buckling and frequency
analysis - making design optimization easy, robust and accurate.

Capabilities
Design
OptiStruct’s award-winning design synthesis technology
uses the topology optimization approach to generate innovative concept
design proposals.
In the initial phase of the development process, the user
enters package space information, design targets and manufacturing
process parameters. OptiStruct generates a design proposal which is
optimized with respect to the given design targets.
In sheet metal parts, beads are often used to reinforce the
structure. For a given maximum allowable bead dimension, OptiStruct's
topography optimization technology will generate an innovative design
proposal for the ideal bead pattern of reinforcement.
Analysis
Altair OptiStruct's analysis module uses the latest
element formulations available and a fast, robust sparse matrix solver
for linear static, frequency, buckling or simple contact problems. With
its large spectrum of solutions, material models and element types,
OptiStruct covers the majority of all analysis activities performed by
today's manufacturers.
A variety of elastic material models are provided for:
isotropic, an-isotropic and orthotropic material types for shell and
solid elements formulations. Composite structures can also be simulated
with OptiStruct. A full range of beam, shell and solid elements ensure
that complex geometries can be modeled.
OptiStruct’s high accuracy has been proven by numerous industry standard comparisons such as "Standard NAFEMS Benchmarks".
Optimization
Analyzing the performance of structures is
usually only the first step for engineers. More often than not, they
are called upon to make proposals on where and how to modify a part in
order to meet stress, weight or stiffness requirements. OptiStruct’s
seamless integration of state-of-the art gradient based optimization
methods makes size and shape optimization easy.
Shape Optimization
Shape optimization is a methodology to
optimize the shape of existing components. For example, local stress
can be reduced in critical areas by modifying the contour of the
structure. OptiStruct uses HyperMesh's morphing technology to prepare
finite element meshes for optimization. As a result, dramatic shape
changes are possible without mesh distortion. OptiStruct can easily
propose design modifications without underlying CAD data and with
minimum user interaction.
Size Optimization
Size optimization defines ideal component
parameters such as material values, cross section dimensions and
thicknesses. Within the OptiStruct environment, optimization parameters
can be defined with only a few mouse clicks.
Easy model setup, post-processing and automation
OptiStruct
is tighly integrated into the HyperWorks environment. Thus, models can
be set up completely in HyperMesh. Animations, contour plots and charts
can be generated using the post-processing tools in HyperView.
OptiStruct uses the NASTRAN syntax to ensure closed simulation process
chains. Moreover, jobs can be easily automated using a powerful
automation and data management layer available in HyperWorks. |
