Overset Mesh and CFD Simulates a Clean Room Smoke Test

clean room environmentRecent innovations in ANSYS 18 overset mesh have made it possible to use computational fluid dynamics simulations to model the smoke tests that provide useful guidance in designing clean rooms.

Ensuring Clean Rooms are Actually Clean

In the healthcare and electronics industries, process contamination is a primary concern. They manufacture these sensitive products in clean rooms where the concentration of airborne particles is controlled to specified limits. For example, a Class 100 clean room keeps particles of 0.5 microns or larger to less than 100 per cubic foot of air. Even in these controlled environments, particles are constantly being created and can settle on and contaminate surfaces and products.   Continue reading

NVIDIA Quadro GP100 Delivers Superior Performance for Transient Electromagnetic Simulation

Nvidia Quadro GP100NVIDIA recently announced its ultra high-end Quadro GP100 graphics card in February. Comparing to previous generations of Quadro cards, the new card runs much faster and is more power efficient. The new GP100 GPU has 3,584 CUDA cores, which deliver 10.6 and 5.3 teraflops floating point performances for single- and double-precision, respectively.

The GPU is also equipped with 16 GB HBM2 (the 2nd generation high-bandwidth memory) which allows data to be transferred at a lightning fast speed of 720 GB/sec. Both factors enhance the performance for running the most demanding transient electromagnetic simulation.

ANSYS 18 Innovations for Electronics Cooling

electronics cooling of mobile devicesAs digital electronic devices continue to shrink and put greater functionality within consumer and enterprise products, thermal management continues to grow as the bottle neck for defining next generation architectures. Significant challenges exist today because the heat being generated continues to rise while the thermal envelope remains constant for silicon devices.

While some switching power converters have moved to III-V semiconductor materials such as GaN, the overall system still contains many silicon semiconductor devices that must meet traditional thermal envelopes. The removal of this heat has become a critical aspect of the design process, often being a very significant driver of what can be delivered within an electronic product. Continue reading

What do Paris, Composites Curing and Baking Have in Common?

composites curing JECA week from today we’re heading to Paris. Not to see the incredible sights or enjoy some of the museums but to attend JEC World. It’s one of, if not the, biggest composites event. ANSYS will be there to talk with customers and attendees about the simulation of composite and composites curing. There will be whole team of us there so please do drop by ANSYS booth S72 Hall 6 and say hello.

Composite technology has moved forward a great deal since it started making regular appearances in motorsports and aerospace. I’m sure there will be lots of discussions on the challenges people are facing next week. Continue reading

Pipe Simulation Using ANSYS – A Quick Introduction

pipe simulationPipe exist everywhere. There are a wide range of applications involving pipes. For daily life, pipes are used in the water line for our house, the air conditioner of the car we are driving, and in the gas station where the gasoline and diesel are transported. Industry-wise, a lot of pipes are used for processing, gas and liquid transmission, transmission as well as extensively in power plants. power plants.

From a structural analysis point of view, a pipe is a slender structure with a tubular cross section that could be very long along the length direction. A beam can also have tubular structure, but most beams or columns are used for strength purposes. The dominant function of the pipe is used for transporting fluids and gases. The liquid/gas transporting could be hot, under high pressure, and also be viscous. We want to use a minimum pipe thickness to save material while still satisfying the temperature and pressure requirements. Continue reading

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

Bringing the World of Embedded Systems and Software Tools Together: Embedded World 2017 Preview

embedded systems embedded world 2017Spring is just around the corner in many parts of the world and so is Embedded World 2017, which takes place on March 14-16 in Nuremberg, Germany. Embedded World brings together over 30,000 professionals focusing on embedded systems and software tools, and I’m pleased to let you know that ANSYS will be attending again this year in booth 4-303.

We talk about product complexity and how the product development process is changing quite a bit here on the blog and the same holds true for the embedded sector and embedded systems and software tools. More and more products are controlled by embedded software and this software must behave as planned. This not an easy task.

Geometry Scripting in ANSYS SpaceClaim for Rapid Model Changes

Geometry scripting, macros and batch files are great ways to automate repetitive tasks or reduce a complicated workflow to a single mouse click. Although you may have never written or recorded your own script, there’s a good chance you’ve benefited from one created by someone else.

ANSYS SpaceClaim recently introduced a geometry scripting environment that further eases common geometry related tasks. More specifically, it’s a simple way to record or write a set of commands that will automate repetitive tasks or make complicated workflows easy. It also serves as a method of extending the user interface to make otherwise impossible geometry by expanding the different things you can do with geometry. From replaying recorded changes on imported models to parameterizing variables only thought possible in a feature-based system, scripting is a powerful ally in making smart, robust geometry.

Driving Toward the Future with AUTOSAR Compliant Software

autosar complianceToday’s automotive systems are more complex, smarter and more autonomous than ever before, featuring functionality that no one could have imagined 10 years ago. Advanced sensors and electronics control everything from a vehicle’s speed and position to its entertainment and communications technologies. Radar, cameras and other sophisticated electronics are increasingly being incorporated into consumer vehicles.

In fact, today, more than 60 percent of a car’s cost comes from its advanced electronics and software systems. Since many of the functions guided by electronic systems are mission-critical, it’s essential that all automotive systems work together with complete reliability. The tens of millions of lines of software code that control these systems must be flawless. Continue reading

System Simulation for Model-driven Automotive Health Monitoring and Predictive Maintenance

Rather than just listing all the new capabilities for system simulation and analysis in the latest release of ANSYS Simplorer, I thought it would be interesting to share a cool example of how our systems capabilities have been applied to health monitoring of an automotive braking system. And along the way, I’ll highlight how the advancements in ANSYS 18 help our customers model and simulate systems such as these.

This example illustrates a physics-based system model intended to support health monitoring and predictive maintenance of automotive braking systems. And while this is an automotive example, our customers throughout different industries are developing similar capabilities to monitor and manage the performance of their products in operation — all in the name of improving safety, performance, and overall customer satisfaction.  Continue reading
