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

Stronger Bike Frame and Colder Water Bottle Designed Using Simulation

Have you ever thought, “I love this product, but it would be even better if…”? Maybe you wish it were more durable, lighter or even more aesthetically pleasing. Perhaps if it had more features, or operated under more grueling conditions, it would better fit your needs. While you may not think about these little things very often, we at Jacobs Analytics are obsessed with these details and believe in perpetual innovation. We have taken the answers to these questions and designed things like a stronger bike frame and a colder water.

The products we use everyday make our lives easier and more efficient; and when they work well enough, we tend not to think much about them. Then one day you come across a better version and realize the product you have been using did have room for improvement, and the improved design makes your daily experience that much better.

Is Uber Actually a Space Company? The Discussion at AIAA SciTech

While attending the AIAA SciTech aerospace event in January I was surprised when the discussion turned to Uber as a space company. Seriously? I understand that Uber is revolutionizing the business model for transporting people, but I thought it was purely terrestrial.

Even though this statement was said somewhat tongue in cheek, with a stretch of the imagination you can see how it can be argued that Uber’s business model is predicated on monetizing data — GPS in this case — that is a product of the space industry. From this follows the (somewhat tenuous) proposition that Uber should be considered a part of this industry.

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

Solution Dependent Expressions for Fan Cooling Simulation with ANSYS AIM 18

In ANSYS AIM 18, design engineers have reason to be excited about increased functionality for fluids, structural, thermal and electromagnetics. While the foundational problem-solving functionality has existed since AIM 16, new functionality is being added in every release so AIM can better address niche applications. One such enhancement I’d like to bring to your attention is solution-dependent expressions for applications like fan cooling simulation. While this isn’t something I guarantee you’ll use in your everyday simulations, it is a powerful feature needed for certain calculations. Continue reading

National Engineers Week – Dreaming of a Better World

national engineers weekIn the United States, National Engineers Week is always the week in February which encompasses George Washington’s actual birthday, February 22. It is observed by more than 70 engineering, education, and cultural societies, and more than 50 corporations and government agencies. ~Wikipedia

When I graduated in 2005 with a Ph.D. in Engineering I did what many of us did at the time: flew to New York City to interview for Quant jobs. That is what was cool and sexy. Financial engineering, not engineering, was all the rage. How times have changed — for the better IMHO. Continue reading
