HyperWorks 12.0 introduced a new Large Scale EigenSolver called Automatic Multilevel Substructuring Eigen Solver (AMSES) in OptiStruct. AMSES is a very efficient and modern solution to run many complex noise and vibration analyses, such as frequency response, transient response, and CMS Super Element creation.
OptiStruct offers a comprehensive optimization package aimed to simplifying the design of composite structures. This package includes three main optimization phases and associated techniques: Concept (free size), Dimension (size) and Sequence (shuffling). This video will focus on phase one, concept design through free size optimization.

Composites are flying high in the aircraft industry as manufacturers look for ways to reduce weight, improve performance and create a better customer experience. Composites, of course, weigh considerably less than conventional aluminum and titanium materials, and they offer a number of other benefits as well. These include high stiffness-to-weight ratios, better fatigue performance, non-corrosive characteristics, and less susceptibility to crack growth.
That said, composites are subject to their own distinct problems. The damage modes are far different from those of metals. Delaminations and matrix cracks are common damage modes, and both can occur internal to the structure with no visible damage on the surface. This poses a problem for inspection, so many aircraft manufacturers are embedding sensors into the structure to detect damage. The manufacturing processes also are much different for composites, necessitating different equipment and tooling. The joining methods for composites require different techniques and analysis methods to design and certify.
HyperWorks now available for Mac OS X
HyperWorks tools become more available to science and creative professions with Mac version
HW-11.0.230-HWSolvers contains many new features, enhancements and bug fixes to HyperWorks 11.0 solver suite including RADIOSS, MotionSolve, OptiStruct and HyperXtrude.
Two University of Stuttgart racing teams recently reported exceptional results from employing HyperWorks tools to simulate vehicle design and reduce the weight of their cars prior to vehicle construction.
The impact of HyperWorks is evident in the victories earned by the Stuttgart teams. In 2011, the Rennteam was rated number one in the Formula Student world rankings and has won 10 single competitions since 2005.
The GreenTeam, with 37 teams participating in the electric category in 2011, placed second in Italy and currently holds third place in the overall worldwide rankings list for the electric competition.
The V1.8b release of the AcuSolve product suite comes equipped with many exciting new features and improvements. This release continues to build AcuSolve’s reputation for providing high quality, fast, and robust solutions by introducing new physical models, techniques to reduce computational time, and a powerful post-processing solution.
HW-11.0.220-HWSolvers contains many new features, enhancements and bug fixes to HyperWorks 11.0 solver suite including RADIOSS, MotionSolve, OptiStruct and HyperXtrude. See the release notes for full details.
HW-10.1-SA1-206-HWsolvers and HW-10.0-SA1-206-HWsolvers were re-released last week to fix an incorrect label shown in the RADIOSS output header section, ALPHA-14516, when running a RADIOSS job after installing the above SA updates. This mislabel incidence does not impact the application functionality, you can continue using the software as it is. This issue has been fixed and you can download the new package and re-install it on top of the current installation if you wish.

This is an introductory course for using OptiStruct for optimization in the product design process. Students will learn optimization concepts and do hands-on exercises for topology, topography, size, and shape optimizations. This two day, hands-on course features:
- Topology, topography, size and shape optimization concepts
- Linear static and normal mode analysis with OptiStruct prior to optimization
- Pre- and post- processing for OptiStruct using HyperMesh and HyperView
- Topology optimization with manufacturing constraints
- Combined topology and topography optimization
- Shape generation using HyperMorph which is a part of HyperMesh
- 2D and 3D shape optimization
- 1D and 2D size optimization
