Design for Simulation then Manufacture

Performing a Computational Fluid Dynamics (CFD) simulation on a detailed CAD model is no fun and, more importantly, it is often near useless. Why? Because given that an engineer has committed considerable time and effort to produce a detailed model ready for manufacture, I doubt they will be happy making additional model changes and the extensive rework that it will entail in response to the CFD results. Design for Manufacture (DFM) has been a successful and widely adopted strategy to reduce product manufacturing costs (bottom line improvement). However, such a focus on manufacturability in isolation from functional analysis and optimization (e.g., we can make a cheap airplane, but will it fly?) is missing a huge opportunity to provide enhanced functional capabilities for which customers are willing to pay a premium (top line improvement).

Rather than the Design for Manufacture mantra, I suggest a better approach is to adopt Design for Simulation, then Manufacture, where simulation could be any combination of stress analysis, CFD, etc.

CFD Bid Modeling

Kenneth Wong's Virtual Desktop over at Desktop Engineering ran an interview in May 2010 with Blake Courter and Jeff Waters from SpaceClaim. Blake and Jeff suggested that adding a customized 3D model to an engineering contract bid significantly improved the bid's chance of winning a contract. They coined the term Bid Modeling to describe this process. I think this same idea can be extended to Computational Fluid Dynamics (CFD) consultancy contract bidding - let's call it CFD Bid Modeling.

Caedium Slide Shows

I've just discovered how to share Google Docs, so I've dug through the Symscape archives and uploaded a sample of Caedium related slide shows. Take a look and tell me what you think.

The Caedium Screencasts

Recently I've been busy recording Caedium screencasts, which you'll find sprinkled among our tutorials. Maybe you've seen them? If not, the entire series is listed below. Now, where's your popcorn?

Website Redesign

For a new year, a new website design. If you are a regular visitor to our website you may have noticed some changes, at least I hope you have! Just in case you need some hints, how about a summary of the changes?

CAE Without CAD is Lame, CAD Without CAE is Blind

As well as dreaming up innovative ideas, small engineering companies and consultancies need access to cost-effective tools that let them explore, optimize, and validate their widgets. There are plenty of Computer-Aided Design (CAD) tools available, but CAD is not enough.

Engines of Innovation

Larger companies often have great difficulty innovating at the product and service level. Often innovation in large companies is solely concerned with business process innovation, i.e., freeing up their rigid hierarchies to better manage their existing business processes. When it comes to new exciting products and services small companies are the engines of innovation in most industries.

Build Your Own 3D Red-Blue Glasses

Did you know that Caedium can produce 3D stereoscopic images of your CFD results? You can view them in real time using red-blue glasses. The only drawback is obtaining a pair of said glasses - well not any more.

Dazzling Fluid Dress

The natural beauty of fluid flow is beyond doubt, just picture water vortices in a stream or smoke rising and mixing with the surrounding air. To reveal the intricacies of fluid flow in experiments, fluorescent dyes are often used. But what do you get when you weave tubes carrying pulses of fluorescent liquid into a dress? A dazzling display of light pulses.
