Nonlinear Response Optimization Applied to Real-World Use Cases
|Warren DiasBusiness Development Manager, OptiStruct|
When we talk of nonlinear response optimization – or any finite element based optimization for that matter – there are two components to it: the solver technology and the optimization technology. Let’s start by briefly talking about the solver technology that’s available with HyperWorks. As you can see in Figure 1, it’s a very broad offering covering structural analysis, highly nonlinear analyses like crash and safety, thermal and CFD technology, systems and MBD simulations and last but not least, manufacturing simulation. Such a comprehensive offering is required in order to capture all the physics that our designs are subject to, not just as individual solutions but also as integrated and coupled solutions providing an environment for multiphysics analysis. Note that this integration can be at multiple levels depending on the physics needed to be captured.
An Introduction to Multi-objective Optimization
In this short video our very own Uwe Schramm, Managing Director at Altair GmbH, will discuss what the available options are when a multi-objective optimization problem – often presenting two or more contradicting objectives – has to be solved.
Using Morphing Technology in HyperMesh
This month Erik Larson’s video will guide you through some of the key capabilities offered by HyperMesh for mesh manipulation. While morphing has been introduced many years ago in HyperMesh, and several clients have already taken advantage of this powerful feature, we still like to define it as “The Best Kept Secret for Cutting FEA Re-design Time by 2x to 10x”.
Aerodynamic Development of a Road Cycling Helmet with AcuSolve
CFD analysis is becoming a tool of choice in the competitive cycling industry. Cycling product development has taken advantage of integrating CFD in its development process. Significant improvements were made, mainly for drag reduction. CFD also serves the marketing department: multicolored CFD pictures and other engineering data is now the standard for cycling products promotion.
Following this trend, Louis Garneau Sport, with the help of Lx R&D, included CFD in the development of the Course, their most aerodynamic road helmet to this date.
Do You Need Answers to Key Thermal Design Questions Before Your Idea Goes to Production?
RadTherm can provide these answers starting as early as the conceptual phase all the way through validation by predicting the full heat transfer solution for your product or system. From the temperature or heat rate results, you can modify your system or component design and test the system’s response to the change with benchmark speed, accuracy, and flexibility.

To select solid elements that are on a surface (adjacent to a surface)
Elements by face will work only for shell elements (2D) and so will selection – by geoms > surfaces (these options, for solid elements, will be incorporated in the upcoming versions.) To select solid elements which are on a surface (adjacent to a surface) Do the following.
