Seeing is Necessary to Gain Understanding. Understanding is the Key to Innovation...and We Need it Yesterday

It may not seem profound to say that innovation is the key to differentiating your company from your competitors. But there is more truth to this statement than ever before. For several years now we've given substantial attention to improving quality, and we occasionally talked about innovation. But today, customers assume they'll get quality. Quality is a given. Look at cars. Not too long ago, 100,000 miles was the death knell for cars. But today, cars can easily last 200,000 miles without missing a beat.


With quality being brought under control, progressive companies realize innovation is the next step to gaining competitive advantage. First, innovation can produce the "surprise" and "delights" customers love. Second, innovation can enable a company to corner the market in a certain area and block out competitors by strategically patenting the innovation space.

If fluid flow and heat transfer are critical drivers for your company's products, Computational Fluid Dynamics (CFD) and the resulting visualization are key enablers for fluid/thermal component/system innovations. Without CFD, understanding fluid (air) flow is like grasping the wind. You see where the wind goes, but you don't know where it came from or why it goes there. It's pretty hard to innovate without understanding. On the flip side, when you visualize the flow, you can generate new ideas amazingly fast.


Because speed is critical in today's competitive climate, the next step in the innovation process is evaluating your new ideas quickly. In the CFD world, this means generating, solving, and analyzing models and results fast. CFD and "fast" may seem like an oxymoron, but there are several features in Cradle's flagship SC/Tetra software designed to speed the CFD process.

SC/Tetra is unstructured grid, general purpose CFD software that contains all-in-one pre-processor, solver and post-processor. The software is fully integrated with common interfaces. SC/Tetra is able to read a wide variety of geometry formats. It also contains integrated capabilities to diagnose, repair, and refine the geometry when needed. The SC/Tetra pre-processor uses a robust hybrid mesh generator with octree-based resolution control that provides maximum grid control when refining the mesh.

Precise spatial grid control is imperative for putting cells where they are most needed and refining the mesh in critical regions. Many mesh generators provide grid control on the surfaces but provide virtually no control in the middle of the computational space. This is a major of advantage of the octree mesh generator. It enables the user to control grid placement and density throughout the flow region speeding the solution convergence process.


SC/Tetra uses a very low memory consumption solver (5M cells/GB of RAM). This enables the user to run higher resolution models that capture essential details and improve accuracy, while keeping run time to a minimum. Combined with the fact that SC/Tetra has been developed, since its inception, to run on PCs enables CFD engineers to harness maximum computational power from their existing computer hardware.

SC/Tetra contains sophisticated capabilities that facilitate specialized simulations. It is able to model free surfaces, moving objects, human body thermoregulation, cavitation, aeroacoustics, sprays, and much more.


Over the past few years, CFD has become a more accepted as a design tool. But it's real strength is in evaluating new concepts and driving the generation of new ideas. This is one of the significant innovation enablers you need to move your company's products ahead.
