ANSYS Maxwell 18 – Conquer the New Demands of Electromechanical Design and Power Electronics

As you can imagine, there are many conversations at ANSYS centered around the simulation industry and current engineering trends. Sometimes during the conversations with my colleagues that handle the microwave and RF communication and signal and power integrity sectors of our business, I get the feeling that electromechanical design and power electronics is boring. Why do we want to talk about simulation of devices that have been around for a century like electric motors and transformers?   Continue reading

SGI and ANSYS Achieve New World Record in HPC

Looking back at the past couple of years of extraordinary joint engineering projects SGI and ANSYS have undertaken, it is clear to me that when a synergetic hardware and software partnership is established you, our joint customers, are the clear beneficiary. To that end, I would like to walk you through four such examples.

The first example was outlined over a year ago in my ANSYS guest blog, “Solving the Impossible Electromagnetic Simulation with HPC” where with a “grand challenge” benchmark we jointly demonstrated that the SGI® UV platform and ANSYS HFSS software could solve very large, high frequency electromagnetics problems like cosite analysis and radar cross section (RCS) analysis, as well as allow multiple frequency sweeps to be run without running out of computer system memory.

New Technology Radically Speeds the Simulation of Transient Electromagnetic Fields

Transient Electromagnetic SimulationElectric machines, power and electronic transformers and other devices can be better designed and analyzed using transient electromagnetic field simulation. This choice allows engineers to analyze the dynamic system including the non-linear materials, permanent magnets and induced eddy current under a variety of conditions, employing various excitations including the pulsed waveform.

Wireless Power Transfer (WPT)

Wireless power transfer (WPT) is much researched and discussed in the context of IoT, electric vehicles and mobile electronic devices. The methodology of powering a device without a physical connection is well known. However, designing the coil shapes and their placement, maximizing efficiency and validating behavior at the system level still represent challenges that cannot be achieved without simulation. The next frontier to be explored is extending and applying wireless power transfer systems to more applications, such as continuous charging of multiple devices, increasing the range of efficient power transfer and ensuring the WPT system design meets regulatory guidelines.

Advanced Electric Machine Design with Electromagnetic and CFD Simulations

You may have read a quick blog post at Desktop Engineering about ANSYS’s electric machine simulation capabilities. Here we dive into the technical aspects and implications of thermal simulation for electric machines.

Electric machine geometry with cooling and integrated power electronics.

Electric machine geometry with cooling and integrated power electronics.

Modern electric machines are designed to meet a wide range of applications, all facing a variety of different technical challenges. They are designed to be compact with high power densities, to have integrated power electronics, to be high-speed for higher power density, and to handle harsh environments.

These challenges all have thermal implications that affect the lifetime and performance of the electric machine and power electronics, and must be balanced with cost goals. ANSYS simulation tools, Fluent and Maxwell, can be used to predict the thermal and electromagnetic performance of these systems, and can therefore be used to optimize design choices for both thermal and cost considerations while meeting all application objectives.

ANSYS 16.0 Targets Electromechanical and Power Electronic Design

Vehicle electrification, renewable energy, and power delivery applications continue to be major trends driving innovations in the industrial, automotive and aerospace sectors. “Good old designs” of power systems and electrical machines using a build-and-test methodology are out of date. Products using the old approach are filled with inefficiencies, are over-designed, and do not include electronic controls. These applications such as automotive electrification, automotive infotainment, and power electronics across many industries are driving the need for new ways of thinking and new design flows. ANSYS 16.0 delivers! Continue reading

Magnetoelasticity: A 20-Year Journey from Cornell to Michigan Tech to ANSYS INC.

I was reminded of Professor Francis Moon, Joseph C. Ford Professor of Engineering Emeritus, when I visited Cornell University this summer for the 2014 Engineering Development Forum. You see, 20 years earlier I had just completed my PhD dissertation in the area of magnetoelastic buckling, a topic that was initiated by Professor Moon in 1968. His breakthrough research created immense interest around magnetoelasticity in the research community. Continue reading

Designing Motors with a Coupled Simulation Approach

Last year, the company I work for — CFX Berlin (an ANSYS channel partner) — was selected as runner-up in the ANSYS Hall of Fame competition. The application we submitted was about designing motors with a coupled simulation approach, based on work we performed with a customer. When ANSYS asked us to participate in a webinar on this topic, we were happy to share what we learned.

ANSYS Hall of Fame 2013 runner-up CFX Berlin

The company we supported was Anhaltische Elektromotorenwerk Dessau GmbH (AEM Dessau), an electrical motor factory in Germany. The business is shifting from traditional development processes to true simulation-based product development for rotating electrical machines. The integrated electromagnetics and fluid dynamics (CFD) software from ANSYS makes it possible to perform real multiphysics calculations for these machines.

I’ll give you a little background on this project. AEM Dessau has more than 60 years of experience in producing rotating electrical machines. The company produces user-friendly, innovative and safe products that meet the highest standards of quality and reliability.  It is not only a supplier but partners with their customers to help them compete in this market space.

4:00 pm EST, 9:00 pm GMT (REGISTER)

A typical simulation workflow requires reading geometry, cleaning it, creating a closed body, generating mesh and reviewing mesh quality. For having a hex dominant mesh, additional geometry decomposition steps may be required. This process can be tedious.

In ANSYS 14.5, there are host of new features in ANSYS DesignModeler (DM) and ANSYS Meshing (AM) that makes preprocessing faster, more efficient and hence resulting in improved productivity for CFD and Mechanical workflows. These enhancements include support of newer CAD releases, usability for DM and AM, improved performance while dealing with large sized CAD geometry and hex dominant mesh in AM. Continue reading
