Many studies on automotive mass reduction have been undertaken over the years by various steel, aluminum, magnesium, and composites consortia, all expounding the virtues of substituting a particular material. Altair has participated in studies with all these organizations over the years and has understood the strengths, limitations, and constraints of working with various materials.
Since its release in early March, the eagerly awaited latest version of Altair’s CAE suite, HyperWorks 12.0 has been making work easier, faster and simpler for designers, engineers and analysts, who rely on the suite’s new functionalities and user productivity advancements in product optimization, finite element modeling, multi-physics analysis, powertrain durability analysis, lightweight design and dozens of other new features.
In particular, HyperWorks 12.0 represents significant advancements in three capabilities: design and engineering speed, streamlining complexity and improved product strength. Altair technology leaders have outlined the importance of these elements in product design and the ways that HyperWorks 12.0 can boost the performance in all three areas.
Script 262: Select node by distance
This HyperMesh script detects all the nodes that are below a certain distance entered by the user (from an initial node). The found nodes are placed in a set.
Script 983: Batch HyperMesh for DOE-optimization
This script links a DOE-optimization tool (HST or any other similar tool) with HyperMorph.

Altair has been a leader in technology and expertise to develop safer automobiles and reducing potential injury to passengers. That experience now is helping Altair create safer seating systems for airplanes. Altair recently presented some of its work for the CompositesWorld Aircraft Interiors Conference in Seattle, an event that is covered in a recent blog entry.
Altair’s optimization technology is being applied to the design of the seat frame. We all have seen the seat frames that connect the seat to the floor beams. The seat frame must withstand the static load of the passenger weight but also be able to withstand dynamic loads in case of a hard landing, extreme turbulence or a water landing. Generally, the seats are required to withstand 14-g and 16-g loads.
Danish Team Uses HyperWorks to Prove the Value of Topology Optimization for Concrete Architectural Structures
Denmark’s Aarhus School of Architecture was interested in exploring the potential of applying the kind of simulation-based topology optimization used in the automotive, aeronautical and naval industries to architectural concrete structures and coupling it with robotic fabrication of polystyrene formwork for concrete casting. Led by Per Dombernowsky, who served as project manager and engineer, and Asbjørn Søndergaard, who headed the project’s design and optimization aspects, the combined academic and industrial team created the Unikabeton Prototype project.
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.
The mesh subpanel found in the Options panel allows you to change default meshing behavior, such as when performing an automatic re-mesh of geometry that has been edited to change its topology. Mesh subpanel can be found in Preferences Meshing options.
Topology revision is one of the parameters in the mesh subpanel which determines what to do when you change the model geometry’s topology.
Topology revision includes:
1) Keep mesh: keep the model’s existing mesh.
2) Delete mesh: delete the model’s existing mesh.
3) Remesh: automatically remesh the model using default values.
4) Advanced remesh: maintains node associations with surfaces (normal remesh may not always retain node/surface associativity, which may result in orphaned elements).

The consumer electronics industry has a more dramatic effect on our lives today than at any other time in history, and the pace of change in this industry is mind-numbing. Never have you seen such a passionate demand and obsessive need for the latest electronics gadgets, and never have these devices occupied such a large part of our time and thoughts. They have truly become our gateway to the world.
Advancing technology has made possible many things that once seemed impossible. Looking back 20 years when the first smartphone, the Simon, was introduced by IBM, who could have imagined how much our lifestyle would be changed by smartphones? Looking forward, what will our world look like 20 years from now? It is probably beyond our imagination. Modern technology in the electronics industry moves so fast and furiously that technologies we view as advanced and bizarre today may become so ordinary that we will take them for granted as commonplace.
Consumer appetites have never been so high, as they constantly look for unique new products, while always keeping an eye on price. The pressure on electronics companies to deliver innovative products quickly at lower cost is intense, and they compete furiously to dominate the market. (more…)
