Celebrating International Women in Engineering Day – Friday, June 23rd

Dr Shini Somara Women in EngineeringToday we celebrate International Women in Engineering Day. Recently, I had the opportunity to meet with Dr. Shini Somara over coffee one afternoon. Shini is a broadcasting science and technology journalist who reports engineering and innovation on television and online, both in the UK and USA for networks such as the BBC and PBS. She began her career as a fluid dynamicist, having studied mechanical engineering at Brunel University and has always been passionate about making the invisible, visible!  An interest that began with Bernoulli’s equation and has continued through her communication of science.  

When we met, we started to share some common views about how to encourage more engineers into this field. Dr Somara is well placed to discuss this with her tireless work advocating STEM education, including providing free online education on physics, through a 48-episode series called Crash Course: Physics Continue reading

Learn How Simulation Speeds Turbomachinery Development: TurboExpo Preview

Turbine blades of turbo jet engine turboexpo

I was reminded just how complicated and expensive it is to develop a jet engine when I came across a video describing GE’s recent $26 million Cdn investment to upgrade its Winnipeg test facility. That is on top of even bigger investments by Rolls-Royce ($50 million) and GE ($40 million) and in recent years. Physical testing is not only expensive, it is time consuming and can lengthen design cycles.

Meanwhile, it has become easier than ever to simulate engine performance prior to any physical testing. Improved techniques like harmonic analysis, turbomachinery-specific workflows and better validation coupled with faster, more capable high performance & cloud computing are quickly expanding simulation so engineers can be confident in their designs before the first prototype is ever built. While physical testing is not going away anytime soon, ANSYS is working on digital prototyping with leading turbomachinery companies and helping them to cut it down to size. Continue reading

Simulating Accurate Combustion Dynamics with Lean Premixed Combustion

Stringent emission regulations force the gas turbine combustor community to come up with new designs. Lean Premixed combustion (LPM) is gaining popularity to meet the emission regulations. However, lean combustion process is prone to other issues like combustion instabilities and noise.

Self-excited combustion instabilities in a gas turbine play a vital role in the lifecycle of combustor, noise generation and pollutant formation. If the instabilities in the combustor dominate at natural modes, there are risks of resonance that can lead to bursting damage to the combustors. Therefore, it is necessary to understand the combustion dynamics performance of a given lean premixed combustor. Continue reading

ANSYS and Synopsys Announcement at DAC 2017 – #54DAC

ansys synopsys partnership semiconductors DACSemiconductors touch every aspect of our lives — from the computers that we work on to the automobiles we drive to the medical devices that keep us healthy. As these amazing chips become smaller and more packed with functionality (the latest NVIDIA graphics chip has 21 billion transistors!), designing and producing them becomes far more complicated. Yet increased demand for smaller, more powerful integrated circuits is increasing so companies can create the products of the future. Continue reading

Accelerating Multiphysics Multi-Scale Signoff at #54DAC

Fast, Accurate and Reliable Turbomachinery Simulation with Harmonic Analysis – Meet me at the Turbo Expo to learn more!

Transient blade row simulations in turbomachinery are needed either to improve the aerodynamic performance predictions or because the flow interaction we are trying to resolve and predict is unsteady in nature such as aeromechanical, aerothermodynamic or aeroacoustic interactions. Because the blade pitch is not similar between the rows of turbine or compressor, a transient blade row simulation will usually require the modeling of the full wheel (or full geometry). This constraint renders these simulations not practical and in many cases prohibitive as analysis or design tools. Continue reading

ANSYS on Capitol Hill: Simulation is An Important Component to Solve the Global Healthcare Issue

Over the last six months, significant progress has been made to foster Transatlantic collaboration in the area of in silico medicine. I say significant because the collaboration is now being fostered beyond the technical level. It is happening at the regulatory and policy levels. On October 11th, 2016, the U.S. FDA spoke at the European Parliament as part of an inauguration event for the Avicenna Alliance, the association of predictive medicine, of which ANSYS is a founding member. Last week, the collaboration was reciprocated. The Avicenna Alliance was invited by the FDA and by the staff of Senator T. Cochran to discuss the role of in silico medicine in both a technical context at the 2017 BMES conference and also at the policy level on Capitol Hill. Continue reading

Interactive Script-defined Tools Change the Game in Modeling

If you turn on the TV or browse the internet these days, automation is a familiar topic. From smart homes to learning thermostats, the drive to save time and effort by automating repeated tasks is everywhere. We use words like ‘smart’ to indicate that our devices are no longer one-size-fits-all but instead adapt and can be programmed to better suit our needs and behaviors. So, too, should be the case with our engineering software! That is why we have spent over a year to add scripting, a broadly applicable interface for automation and customization of modeling, to the ANSYS SpaceClaim geometry modeling environment.

In a previous blog post, we introduced SpaceClaim scripting and how it can automate repetitive or tedious tasks. With ANSYS 18.1, we’ve taken it a step further and made it easier to share and use SpaceClaim scripts outside of the editing environment. By publishing scripts to dedicated buttons in the user interface or calling them from within a Workbench script, you can now use the power of scripting in more places than ever before. Furthermore, we have extended the interaction with scripts to allow for user input of selections and values during execution. Let’s take a closer look at these improvements. Continue reading

Free Download – New ANSYS Student Product Downloads Released

Who was it that said “Nothing in life is free?” Whomever it was, they were wrong. There are a ton of amazing things in life that are free — including our ANSYS Student Version products! Speaking from experience, there has never been a time I have appreciated something free more than when I was a student working my way through college.

In late 2015, we launched our ANSYS Student free download, and since then have released several updated versions. Just recently we made some exciting changes with our new Student Product page boasting two new ANSYS Student Products for Windows x64: ANSYS AIM Student 18 and ANSYS Student 18. Both are now renewable, 12-month product licenses with a shorter and simpler download process. Best of all, we’ve eliminated the need for you to fuss with a separate download key! Continue reading

Digital Prototyping for More Powerful Pumps

Routine maintenance of sewer pipes is necessary to prevent clogging, cracking and failure in the long run, saving sewage companies considerable time and money. FMC Technologies, which makes reciprocating pumps used to force water at high pressure through sewage pipes to clean them, turned to engineering simulation to design their latest product when customers began demanding smaller, lighter pumps with a higher output pressure. These pumps would be easier for the operator to move and place for optimal operations in the field. Also, reducing size and weight would make the pumps less expensive to purchase, easier to maintain and more energy efficient.
