Designing a Robust Electronics Product: The Smartphone

smartphone drop testAt last year’s ANSYS Electronics Simulation Expo conference in Japan, my colleague Sandeep Sovani was delivering a keynote when he took out his Samsung smartphone and purposely dropped it on the stage! He was confidently making a point about designing robust electronic products.

The fact that a minor impact didn’t damage his phone’s exterior or degrade the performance of electronics, as best as we can tell, provides testimony that today’s engineers are paying close attention to product reliability and robustness. Continue reading

Mad About Designing a Smartwatch?

Click image to see his 2 watches in action

Jim Cramer is the host of Mad Money. I watch his high-energy, entertaining, investment show regularly. “Booyah!”. Yesterday, I was surprised to see his wrist loaded with two watches. As he didn’t explain, I can only guess as to why he was sporting his Apple Watch along with an analog timepiece. Continue reading

Accurate Spray-Wall Interaction Predictions with ANSYS Fluent 16.0

Computational Fluid Dynamics (CFD) has become an integral part of product design and development. Today, CFD is extensively used across industries like Aerospace, Automotive, Marine, Oil and Gas, Electronics, Health care, Process and Infrastructure. While CFD tools provide detailed engineering insights and shorter product development cycles at reduced cost, CFD community is constantly working hard to improve accuracy, speed and ease of use of these tools. Complex physical phenomenon such as detailed chemistry, primary atomization, electro-chemistry, icing formation are constantly investigated and newer, better and accurate numerical models are introduced in CFD tool.

Automotive, the Ultimate Connected ‘Device’

The Internet of Things (IoT) is about connected devices, and those devices are not just smartphones, tablets and phablets. It is anything that can collect data (sensors), connect to the internet and transmit the data wirelessly (antennas), and make smart decisions on acquired data (embedded software / processors). The biggest “mobility device” happens to be one that is near and dear to Americans — the car. Over the last few years the amount of electronics and connectivity within a car has been rapidly growing making it a primary differentiator for an automobile. Continue reading

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

GPU Acceleration of ANSYS HFSS Transient at NVIDIA GPU Technology Conference (GTC) 2015

The paradigm of supercomputing has shifted rapidly during the past decade. Ten years ago when we heard “NVIDIA”, immediately we associated the brand name with computer graphics, games and animation. NVIDIA’s breakthroughs in graphics processing unit (GPU) technology make supercomputing inexpensive and widely accessible nowadays. In addition to its visual computing leadership, NVIDIA also strives for green computing where its hardware design aims at the best performance per watt. More than eight teraflops of computing power can be achieved on an NVIDIA Tesla K80 that consumes less than 300 watts of electricity. Continue reading

ANSYS HFSS Delivers for IoT, UAVs, Drones and Wireless Communications

The explosion of the Internet of Things (IoT), unmanned aerial vehicles (UAV) and continued proliferation of mobile communication devices is driving the demand for simulation tools to design and integrate antennas on complex structures and platforms. In addition is the need to design radio components and systems used in these mobile wireless communication devices. With the release of ANSYS HFSS 16.0, we deliver a new interface with advanced design and solver technology that allows users to design and optimize these wireless components and systems and leverage them throughout the complex supply chain. Continue reading

Tackling Next Generation CPS Design Challenges

System design and even system integration have taken on a whole new meaning with the latest trends in mobile and wearable computing. Integrating the compute power formerly associated with super-computers into a wrist band puts entirely new challenges on engineers, as they struggle with ensuring  signal and power integrity, as well as controlling the thermal profile. For these next-generation designs, full system analysis in the form of a Chip-Package-System (CPS) co-analysis is not an option anymore — it is an absolute necessity in order to achieve convergence.
