EnSight, the leading post-processor for Computational Fluid Dynamics (CFD) data is now part of ANSYS. In the two decades since its launch, EnSight has taken off like a multistage rocket. Here is the story.
I grew up in that magical era when NASA used multi-stage rockets to carry Apollo astronauts to the moon and back. As a toddler I learned to count backwards from 10, 9, 8, 7, 6 … because that’s what I heard Mission Control say. I dreamt of being an astronaut, studied aerospace engineering and started my career at NASA’s Johnson Space Center in Houston, Texas. I met my lovely wife there, blocks from the NASA gates. Her parents still live next door to Buzz Aldrin’s Apollo era house. I used to store my lunch in the Mission Control fridge while working on my space shuttle aerodynamic simulations in the support room next door. So maybe it’s natural for me to think in rocket terms.

Today, after a video call with my kids at home, I feel more relaxed. Usually on long distance business travel, we are always concerned about the family at home. A few years ago long distance voice calls were not only costly but also of poor voice quality. Now, equipped with mobile phones, we can make high-quality audio/video calls and exchange text messages with people around the globe, at little or no cost.
It’s amazing to see the way communication technology has grown over the years. Technologies that seemed like fiction a few years ago, are now becoming reality. These include virtual reality, 3-D hologram and printing, language translation, and mobile streaming audio and video. Continue reading
Every numerical method relies on the accurate choice of models, solver settings, and material parameters in order to be able to mimic real-world behavior. This also applies to Discrete Elements Method (DEM) simulations. You could use standard material properties, but adjusting those material interaction parameters using automated calibration methods is a key step for accurate simulations.
You could use standard material properties, but if you want to simulate reality, it is important to understand that the materials actually vary from site to site. Adjusting those material interaction parameters using automated calibration methods is a key step for accurate simulations. Even with basic materials, friction and restitution coefficients between particles and particles and boundaries have to be adjusted in order to accurately predict the bulk flow behavior. When extra forces come into play, such as adhesion forces, those additional parameters also need to be selected and properly specified. Continue reading
In June, I attended the Design Automation Conference in Austin, TX and LiveWorx in Boston, MA. I would like to share some key observations from both events.
- The Internet of Things is going to be big; very big!
- Success requires partnerships.
- IoT is about monetizing data.
- Engineering simulation is essential.
The Internet of Things is going to be big!
At the just concluded Design Automation Conference in Austin, speaker after speaker stressed this.
Silicon Labs CEO, Tyson Tuttle, noted that there will be 70 billion Internet connected devices by 2025 with accompanying semiconductors to power them. He repeated McKinsey’s forecast the the Internet of Things will drive between $4 -11 trillion in global economic impact by 2025. Continue reading
About 6 weeks ago, I attended the NAFEMS Multiphysics and Multiscale conference in Columbus, Ohio, USA. I have witnessed the benefits women in tech bring to their companies and themselves and make a habit of counting how many women are at these events. I am excited when the number of women exceeds 10% of the attendees. This event did not quite meet that benchmark. Most conferences I attend in the simulation space do not. As a woman in tech with a keen interest in increasing the number of women in engineering and technology as well as promoting and supporting those already there, I find this disheartening.

The main challenge of turbulent combustion simulation is to resolve turbulent mixing together with the chemistry of combustion involving hundreds of molecular species, in a solution time that is compatible with engineering design. Steady diffusion flamelet-based turbulent combustion models have been used for nearly three decades. The computational efficiency of flamelet-based models has been the key to their widespread success in industrial applications. However, increasingly stringent emission requirements continuously push designers to incorporate more finite-rate chemistry effects for the engine simulations in a more comprehensive manner.

Unsteady methods are becoming increasingly important in turbomachinery design and optimization because they model transient flows and performance more realistically. Unfortunately, using time-accurate CFD simulations to understand these unsteady flows in compressor stages can be computationally expensive. In recent years, ANSYS has been working on methods for modelling the transient flows in turbomachinery stages that require as few as single-blade passages per row but with equivalent accuracy. As a result, engineers can drastically reduce computational time and memory resources by up to 10X. Continue reading
Industrial IoT and digitization will loom large as the industry professionals gather at this year’s Offshore Technology Conference (OTC) in Houston, Texas, May 1-4. Over the past few years the industrial IoT has grown beyond information technology concerns (gathering data, data processing and security, etc.) and now includes predictive maintenance of assets, prognostics health management (PHM), reducing cost and nonproductive time, eliminating breakdown and failure.
One of the first steps in realizing the benefits of the IoT for the energy industry is to create intelligent machines/digital products. As evident from consumer product devices, for example smart watches, soon if not already, oil and gas equipment will also need to perform more than just a mechanical function and must become smart or intelligent.

We are now in our 6th month of the nearly weekly ANSYS in ACTION webinar series, where we show you how ANSYS software can be used to solve common applications in just 20 minutes using live demonstrations of our software. Several new, upcoming sessions are now posted on the ANSYS in ACTION page. I am also pleased to point out that we recently extended our line-up to include products from across our portfolio.
For example, on April 27, ANSYS in ACTION will feature “Faster Turbocharger Designs with Simulation” where we will dive into using ANSYS TurboSystems to optimize turbocharger designs. Continue reading
LabCentral in Cambridge, MA, is a first-of-its-kind shared laboratory space designed as a launchpad for high-potential life-sciences and biotech startups.
Many claim that engineering simulation in healthcare will be critical. The only way to get a clear and complete answer would be to ask the question “Is simulation essential for healthcare?” to the people using computer modeling and simulation (CM&S) routinely for medical device design, biotech or pharmaceutical process modeling during the ANSYS Healthcare Innovation Conference in Cambridge, MA on May 10th.
