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, …

The Implications of the Cloud for Simulation

All that compute power is enticing, right? It’s a great story. But there’s just one big problem: getting your simulation model into the cloud. And that wouldn’t be a problem if these simulation models weren’t quite so humongous. I mean, you wouldn’t need all that compute power if these simulations were easy to solve, right? …

The Misnomer of Feature-Based Machining

Ever heard of COFES, which stands for Congress on the Future of Engineering Software? Its an event out in Phoenix AZ held by Cyon Research that aims to bring together folks that are media, industry analyst, software provider and users to talk about where computer aided technology is heading.

Is Feature-Based Modeling Now Obsolete?

Gone off the rails have I? Well, even if you think I am crazy, I still think its a fair question to ponder. Even if only for a moment. Hear me out and you might even agree.Over the past three months here at, I’ve hosted three separate webinars on design topics. Back on March 19th, we kicked things off with Clean Sheet Design where we looked at how CAD did or didn’t support new design efforts. On April 16th, we looked at how CAD supports Desig…

Mitigating the Legacy Data Risk to PLM Deployments

Deploying PLM or PDM? Heh. That’s literally a whole different class of software. Many things can go horribly wrong along the way to a go-live date. If you’re leading the deployment of such a system, be ready. There will be surprises along the way. What surprises? Well, let’s discuss.
