ANSYS Fuels Nature-Inspired 3-D Printing

Nature is full of amazing materials. Wood and bone, for example, are natural composites with finely-tuned microstructures. They have optimized fiber alignment for enhanced strength. At Fortify — an additive manufacturing startup — we wondered if harnessing the power of natural composites in 3-D printing could help us to create high-performance end-use parts.

Our observations of the natural world led to the development of our fluxprint technology, which utilizes magnetic fields in a 3-D printer to align carbon fibers throughout a printed composite part. This process results in high-performance components with high-geometric complexity and incredible strength-to-weight ratios. Continue reading

Cloud is Leveling the Playing Field for Technology Startups

A technology startup faces a great deal of challenges: funding, hiring, office space, manufacturing, messaging, legal, software, and infrastructure, to name a few. CEOs can feel overwhelmed by the sheer size and complexity of the puzzle that is establishing a successful corporation. It only takes one of the pieces to fail to jeopardize the whole enterprise. The stakes are high.

One area of investment that is particularly expensive and difficult to get right for hardware startups is the engineering simulation software and high performance computing (HPC) infrastructure required for virtual prototyping and testing. Rescale and the ANSYS Startup Program offer solutions for startups with on-demand and fully scalable software and hardware that require zero in-house IT.

Simulation Used to Spur Design Development for Nuclear Power

Nuclear power is a key player in the future of clean energy, and multiple companies are pursuing new technologies to maximize nuclear’s contribution to the clean energy space. Founded in 2011 and based in Cambridge, MA, Transatomic Power is an advanced nuclear technology startup developing and commercializing a molten salt reactor (MSR), or a nuclear reactor whose fuel is in liquid, rather than solid, form. This technology, originally developed at the Oak Ridge National Laboratory (ORNL) in the 1960’s, offers multiple safety and cost benefits over traditional nuclear reactors, in which the fuel is in the form of solid pellets cooled by water.

Tranatomic’s MSR design builds on the original work at ORNL and adds a few innovative new features that reduce the reactor’s size and, as a result, it’s cost – a huge factor in building new nuclear power plants. Though the development process is a long one, the world needs a larger capacity for clean energy generation, and it’s this ultimate goal that drives the Transatomic team forward. Continue reading

PowerCone™ Wind Turbine Development Accelerated with Simulation

The journey of BiomeRenewables’ PowerConeTM wind turbine started with witnessing a falling maple seed. I was sitting on my deck when I was struck by how slowly the seed was able to fall. As it turns out, maple seeds — for their size — exhibit maximum aerodynamic efficiency; they are able to hit what is known as the Betz Limit — 59.3 percent aerodynamic efficiency. Careful analysis revealed that there is something about the seed’s shape and the way it interacts with the air that allows it to achieve such high efficiency numbers — namely, that it interacts with the oncoming flow at an angle greater than 90 degrees. This is not the case with modern wind turbines, which interact with the wind at perpendicular angles of 90 degrees. Continue reading

Hang Gliding Takes Quantum Leap with Simulation

hang gliding simulation side viewSince its creation, hang gliding has progressed solely — and often painfully — through experimentation. But engineering simulation is starting to change that.

The German inventor and flight pioneer Otto Lilienthal made over 2,000 flights as long as 820 feet in gliders he designed and flew in the 1890s. He died in 1896 from injuries sustained in a glider crash, but his well-documented accounts of theories and experiences with flight influenced many of the early aviation pioneers, including the Wright Brothers.
