Simulations Conducted Within CAD Systems Are Faster, Research Finds

I have always wondered if any advantage that CAD provides to the simulation process could be quantified. Naturally, one would assume that CAD does, in fact, offer some value to simulation efforts. But to my knowledge, that has never been verified. In an effort to solve this mystery, I included several questions on this topic …

The Trend Towards CAD Consolidation, Not CAD Standardization

For years, CAD standardization and consolidation have meant the same thing. But with advances in CAD tools, the meaning of those phrases are diverging.

Leveraging 3D CAD Data

Have you ever read Evan Yares’ stuff? If not, you’re missing out. He’s a really smart dude covering this space. Evan and I got to catch up at the 3D Collaboration and Interoperability Congress, where I presented findings from the 3D Collaboration and Interoperability Study. A couple weeks ago, Evan wrote up his own analysis of the findings in a post titled Leveraging 3D CAD Data. And he didn’t just regurgitate statistics. He provided some pretty deep analysis. And it’s good.

Transition from 2D to 3D Design Hasn’t Been a Clean Break for Most, Study Finds

In todays product-development environments, 3D models play an important role in design as well as the overall development process — there’s little doubt about that. But how far have we really come in the adoption and use of 3D data for product development?

Continuous Systems Validation: Implications for Software Solutions

Continuous systems validation brings a whole new level of complication to simulation. In my first post in this series, we looked at how designs progress in various engineering disciplines. In the second one, we looked at how cross-disciplinary simulations are actually assembled out of these different designs. But furthermore, as the design progresses at the …

Is CAD in the Cloud Truly Terrifying?

For the past three years, the CAD industry has been a really wild and fun ride. The ball started rolling with broad acceptance of Direct Modeling. It’s grown into a full blown peer of feature-based / parametric / history-based modeling. I think that technology has more maturing to complete, but its interesting that just about every CAD application out there now has some form of this capability.
The ball continued right along with 2D tools. We’ve finally seen this industry accept that, in some …

Continuous Systems Validation: System Simulation Configurations

  Ready for more system simulation?Well, strap in. This is where things get complicated.In the last post, we dove into the progressive means of representing and assessing designs in mechanical, electrical and software domains. We found that in each discipline, the representations changed. We also found that the means by which each design representation is …

Continuous Systems Validation: Progressive Design Representations

I now have no doubt left in my mind: system simulation is now all the rage. A few weeks ago, I hopped on the bandwagon to write on the topic. I published a post titled Systems Simulation: Far-off Future or Feasible Now? here at the NAFEMs blog. That post focused on how to build a simulation model that incorporates various digital and physical representations from different engineering disciplines. Its complicated stuff in its own right. In that post, I posed the question of whether were close to reality or some future vision.

Validation Grows in Credibility at 3D Collaboration and Interoperability Congress

  “Users who participate in standards committee deliberations must be patient,” Jackson added. “Solution providers have to incorporate capabilities into future releases of their software to support these new standards. Users sometimes wait for years to see a definition they helped create implemented in the software applications, if it is implemented at all.” Real progress, …
