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…)

When we think of optimization, we naturally think of finding the design with minimum cost, maximum performance, etc. However, we can use optimization methods for objectives other than minimizing or maximizing. One of these use cases is to meet a set of target values; so we need neither to minimize a response nor maximize it. We instead need to make sure that it achieves the target value.
A typical application comprises model calibration problems, such as simulation material model calibration to match to test data. We can formulate these cases as minimizing the difference between sets of data leading us down the path to use optimization methods for efficient and effective solution- finding. How we calculate the difference may depend on the application, but a very common calculation that works well for most problems is to minimize the sum of normalized-difference-squared. Another common calculation may involve calculating the area between two curves.
The first aspect of solving such problems easily is the method selection. The second aspect is the ease of setup, and the third aspect is the post-processing. In HyperStudy, we have an objective function formulation called System Identification. System identification allows users to set target values to a number of responses and automatically creates the difference equation and uses it as the objective function. In the pos- processing site, HyperStudy lists the values of all objectives, the delta between them, and the targets and the normalized deltas. We will now go through an application that uses system identification for material model calibration. (more…)
This short video demonstrates an effective process of calibrating multiple models using design of experiments (DoE) and optimization methods in HyperStudy. We applied this process to calibrate a ductile aluminum alloy modeled in RADIOSS block as an elasto-plastic material using Johnson-Cook model to match to test data.

Wagon Automotive, a system and module supplier of components to major car builders, sought ways to accelerate product development and reduce prototyping costs while maintaining high quality. Adopting the HyperWorks suite of advanced CAE tools enabled the company to achieve both those goals. Wagon Automotive now uses HyperWorks during the entire development cycle, from concept design to optimization.

Multi-Objective Optimization in the Design Cycle
Design optimization seeks a design that minimizes the objective function while satisfying design constraints. Real-world design problems are usually characterized by the presence of many conflicting objectives. Therefore, it is natural to look at the engineering design problems as multi-objective optimization problems. For example, we may want to maximize range and payload mass while trying to minimize manufacturing costs for an airplane design.
