Parametric feature-based solid modeling is almost 30 years old. In that time, not much has changed. Sure, there have been plenty of CAD systems with their own take on how to model in 3D, but the basic principles remain the same: Create a sketch → Create a feature → Repeat.
One of the main benefits of parametric modeling systems is being able to make changes quickly. Every sketch and every feature is driven by dimensions, so all you have to do to make a design change is to change the value of a dimension, right? Yes, in most cases, but if only it were that simple all of the time.
When you create a sketch, you are capturing design intent by adding dimensions, constraints and references to other model geometry. This design intent helps you predict how your models will update when changes occur. However, if you’re not careful, you can easily get yourself into a pickle. Making too many careless references to other geometry in your model can make your model very fragile. If your model has dozens of features, you could end up chasing errors for hours. A lot of this heartache can be avoided if you have a basic understanding of what’s going on behind the scenes.
Every geometric element created by a parametric modeling system has a unique internal ID number. This number is referenced by subsequent sketches, features, assembly mates, and drawings to work out where things should be placed relative to the rest of the model. So if that ID number no longer exists, guess what? That’s right, the feature doesn’t know what to do and fails. If a design change makes an edge or face disappear, it is likely that some downstream features will fail. It’s not the features themselves that are the problem, it’s the references you make between them. References can be your biggest ally, but also your biggest enemy.
Siemens announced an agreement to acquire TASS International, a global provider of simulation software and related engineering and test services primarily to the automotive industry focused on autonomous driving, integrated safety, advanced driver assistance systems (ADAS) and tire modeling. Based in Helmond, The Netherlands, TASS has developed what Siemens terms “a rich family of solutions that will further strengthen Siemens’ product lifecycle management (PLM) software portfolio, and add to its position as the leading supplier of systems-driven product development offerings for the global automotive industry.” The combined offerings, Siemens says, will provide “a fully integrated solution to frontload verification and validation of automated driving systems.”
Commercial building designs from today’s architectural engineering industry are growing ever taller and more elaborate. Currently the world’s tallest skyscraper is the Burj Khalifa in Dubai, UAE, standing at 828 meters (2,717 feet). This commanding height brings a unique set of engineering challenges, one being how to transport people efficiently from the ground floor to the top.
Most elevator systems raise and lower the elevator cabin by means of a motor-driven cable system installed at the top of the building. However, such systems generally afford a maximum ride length of 400 meters (1,312 feet)—just half the height of the Burj Khalifa, meaning passengers would have to board two, or possibly more, elevators to reach the top level.
ThyssenKrupp Elevator, a unit of ThyssenKrupp Corporation, is one of the world’s leading manufacturers of elevator systems, with annual sales of €6.4 billion and more than 50,000 employees at 900 locations. To meet the challenge of efficiently transporting occupants within the Burj Khalifa, the company’s design and engineering teams conceived and developed a novel design that uses electromagnetic drives attached to the frame of each elevator cabin for propulsion. This eliminates the need for roof-mounted cable systems and lets a single elevator traverse the Burj Khalifa’s full 800-meter height. In addition, it allows the elevator cage to move horizontally as well as vertically. But this new concept also brought new challenges, chief among them being that the cabin would not be able to carry as much passenger weight as a traditional elevator. Continue reading →
Two new, seamlessly integrated features in the latest release of Siemens’ STAR-CCM+ software for multiphysics computational fluid dynamics (CFD) simulation and analysis enable automated product design exploration and optimization. One is Design Manager, a capability in STAR-CCM+ version 12.04 that lets users easily explore multiple design options within their CFD simulations. The other is STAR-Innovate, built on the proven technology of HEEDS, the multidisciplinary design exploration (MDX) software that Siemens came to own through its 2016 acquisition of CD-adapco, which had previously acquired HEEDS and its developer, Red Cedar Technology. STAR-CCM+, now developed and managed by Siemens PLM Software, is part of the company’s Simcenter portfolio, a robust suite of simulation and test solutions. See our Predictive engineering analytics: Simcenter unifies, advances Siemens PLM’s simulation/test portfolio.
“I firmly believe that single-scenario engineering simulations are about to become a thing of the past,” says Siemens PLM Software senior vice president of product management Jean-Claude Ercolanelli. “If you know how to use STAR-CCM+, then you will instinctively know how to use Design Manager. This means that every engineer who installs STAR-CCM+ v12.04 can now conduct design exploration studies with ease to discover better designs, faster.”
“STAR-CCM+ is the only multiphysics CFD offering that seamlessly enables engineers to perform design exploration studies backed by an industrial-strength optimization tool like HEEDS,” Ercolanelli adds. “As a result, engineers can spend less time setting up and monitoring simulations, and more time assessing the outcomes to determine what makes good designs great. This is a game-changer.”
HEEDS: The Pro/E of design space exploration
Our firsthand research among users in global automotive, aerospace, gas turbine and other manufacturing industries confirms HEEDS is a breakthrough technology that at last makes multidisciplinary design exploration easily and readily usable by engineering discipline leads, without their having to become experts in the arcana of design space exploration (DSE) tools and methods—design of experiments, response surface models, scatter plots, Pareto frontiers, stochastic optimization, on and on. Or, as is more often the case, hire an engineering service provider with specialized expertise in DSE in order to gain access to the technology’s benefits.
Indeed, we believe it is not too much to deem HEEDS the “Pro/ENGINEER of design space exploration”—bringing to DSE the same generational leap forward that PTC’s then-revolutionary technology for parametric, feature-based 3D modeling represented over the cumbersome, not very usable or practical solids modelers available to that time. HEEDS is the first in a new wave of software tools that promise finally to bring design space exploration out of its two-decade history as a niche technology applied only in extreme situations, and at last make it a practical everyday engineering tool. Other new-generation DSE tools of this ilk include DATADVANCE pSeven, ESI MINESET, ESTECO modeFRONTIER 2016, Noesis Solutions id8, Phoenix Integration’s newest iteration of ModelCenter, and more.

“Digital industrial transformation requires more than just installing new software—it requires the adoption and utilization of new tools and solutions across your enterprise,” says GE Digital, developer of the Industrial IoT platform Predix. “Built by industry for industry,” says GE, “Predix is the Industrial Internet platform that connects your organization’s physical and digital worlds.” For background, see our ANSYS, GE partner to bring simulation to the Industrial IoT.
A new series of “Acceleration Plans” from GE Digital were developed specifically to address this need and drive outcome attainment. “These plans offer a comprehensive set of service capabilities to help you maximize value from your software investments and capitalize on your digital industrial transformation,” the company says. “Acceleration Plans address critical product support, end-user training and education, data health, and overall organizational adoption needs.” Continue reading →
JSP is a global business serving the automotive, construction, civil engineering and packaging markets with a range of expanded polymers. When the company first began to embed plastic and metal components into its automotive seat designs fabricated in ARPRO® expanded polypropylene (EPP), its engineers discovered that this made post-fabrication shrinkage of the product more difficult to predict. The modeling and simulation methods they were using at the time failed to account for thermal effects during shrinkage, making simulations of the manufacturing process unrevealing and unreliable. Consequently, additional physical trial and error were required to achieve the correct final form, stretching out development schedules and driving up costs.
To overcome that problem, JSP adopted ESI Group’s ESI Virtual Seat Solution (VSS). With this new technology, JSP engineers found they can now—reliably and recurrently—define a target shape that includes plastic and/or metal molded inserts, select the density of their ARPRO® foam, then calculate the mold shape that will deliver the required geometry for each component upon completion of the molding and curing process.
