‘DS: Industrie 4.0 is old news; makers and innovators will rule tomorrow’

‘…For me, the most compelling tidbit was CEO Bernard Charlès’ declaration that DS is so over the whole Industrie 4.0 thing. He said that it is “yesterday’s way of thinking, that tomorrow is about ecosystems of makers inventing new things with the end-customer in mind: new services, new content, that industries will offer their clients.” That’s fascinating, because many of the industrial companies I deal with are still very much in the midst of Industrie 4.0. They’re trying to figure out what that means to them, and what/how to digitalize more of what they do and if they even should. …’

Our impression, from the above highly observant note by astute industry analyst Monica Schnitger, plus many months of our own pondering:

Has DS at last thrown in the towel on engineering, and cast its fate instead in the future of its new ‘scientific‘ brands?

Dassaults technological decision to require that, to implement 3DEXPERIENCE and CATIA V6 solutions, client organizations must commit to ENOVIA certainly suggests so, in the face of strong new-adoption preferences among leading engineering organizations for rival data/process management platforms such as Teamcenter, Windchill, and now Aras.

New EDEM/RecurDyn co-simulation solution gives off-highway equipment engineers high-fidelity modeling of bulk material behaviors

Bulk-material simulation specialist EDEM released a co-simulation solution between its software and RecurDyn, the multibody dynamics modeling and simulation toolset from FunctionBay. This new integration enables engineers designing heavy equipment such as excavators, ploughs and off-road vehicles to introduce realistic bulk-material behaviors into their multibody dynamics simulations. EDEM says the new technology offers heretofore unrivaled insight into how material loads are transferred throughout the product’s structure and systems, and provides engineers with essential insights into equipment/material interactions.

Introducing EDEM high-fidelity load values into RecurDyn multibody dynamics simulations frees engineers from hand calculations and guesswork.

New Simcenter 3D v12: Scale, depth, speed of integration progress unsurpassed

Siemens’ newest version of Simcenter 3D, its flagship environment for multidisciplinary computer-aided engineering, offers new comprehensive solutions across multiple simulation disciplines. Key features:

  • Powerful generative design workflows support fully integrated topology optimization and Convergent Modeling for efficient design and simulation.
  • Advanced solutions deliver on Simcenter’s strategy for structural dynamics, motion and acoustics, delivering superior functionality and performance.
  • Improved industry workflows include universal connections support for efficient modeling of large assemblies.

Simcenter 3D is an advanced standalone CAE application for analysts and discipline experts that works with data from any CAD source. Being built on the Siemens NX platform, it of course works seamlessly with NX CAD. With more enhancements than any previous release, the newest Simcenter 3D—part of Siemens’s Simcenter portfolio of simulation and test solutions for predictive engineering analytics—looks to revolutionize how simulation engineers can help drive design direction in industries such as automotive, aerospace and industrial machinery.  See our Predictive engineering analytics: Simcenter unifies, advances Siemens PLM’s simulation/test portfolio.

The new release integrates significant capabilities that were previously available in legacy simulation tools such as LMS Virtual.Lab and Samtech Samcef. Integration and expansion of these capabilities into Simcenter 3D’s unified, scalable and open environment aims to help engineers, analysts and designers improve their overall productivity, and give their organizations access to a broad yet deep array of simulation technology.

Scale, depth, speed of integration work all impress

The scope, scale, depth and—perhaps above all—swift, determined execution of Siemens’ work to intelligently integrate its many CAE-related acquisitions over the past handful of years is unsurpassed by anything comparable we can recall anywhere else in the industry. The latest Simcenter 3D release, and Siemens’ continued progress in realizing its overall Simcenter vision, is testament to the high caliber of both its technologists and its senior management—few companies in any industry can boast the same number of truly world-class executives and experts shepherding and coordinating the various Siemens PLM Software businesses and product families.

What Makes a Parametric Modeler Tick?

What Makes a Parametric Modeler Tick?

By Neil Cooke / August 24, 2017

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.
