Eliminate Football Concussion with Shocking Simulation

Every day between now and February 7th will turn up the excitement about the biggest day of American football, the SUPER BOWL. It will take place right here in the San Francisco Bay Area. Promoters are calling Super Bowl 50 the biggest Super Bowl ever.”  Starting with the Run the Road to the Super Bowl 10K, 5K Run on January 10, to the Metallica and Cage The Elephant concert the night before the big day, events will be hosted to entertain all. This makes me think of football and football concussion.

10x More Reliable Electronic Systems

Reliable Electronic SystemsOn the 18th of February, we’re hosting a webinar showcasing some exciting new methods to increase the number of ways reliable electronic systems can be designed. You can register now but first let me tell you a little about why it’s important.

The proliferation of electronics into every product arena can’t be denied. Electronics bring huge benefits in terms of features and functionality to pretty much any device. This means that electronics are being placed in more varied environments — and subjected to more demanding loads — than ever before. Continue reading

ANSYS ACT Delivers the ANSYS Platform Vision

I’d like to share a video with you that illustrates ANSYS ACT’s three-prong development strategy – product coverage, third-party application integration and enhanced workflows.

Using Explicit Simulations to Go Further

Highly non-linear simulations can be difficult to converge using the implicit simulation tools. The implicit route can involve several restarts trying different settings each time. Another methodology is available for these non-linear simulations that is explicit dynamics. Explicit dynamics can be used to simulate anything from quasi-static simulations to hypervelocity impacts.

wire crimping

This wire crimping analysis (shown above) is highly nonlinear with large deflections and complex contact. With explicit this is easier to set up as we can specify global contact. Continue reading

From Subtractive to Additive Manufacturing

On October 1st, there were more than 2,346 events planned to celebrate Manufacturing Day 2015 — a celebration of modern manufacturing meant to inspire the next generation of manufacturers. Pittsburgh-based Catalyst Connection hosted an event near the ANSYS HQ and a few of our ANSYS team members had the opportunity to attend 2015 Additive Manufacturing for Small Manufacturers. Together with 125 area manufacturers we had the opportunity to listen and learn from a range of experts and industry leaders such as GE Aviation, America Makes, Alcoa, NASA Glenn Research Center, Carnegie Mellon University, and the University of Pittsburgh.

Material Forces for Fracture

Durability and failure investigations of products are of high interest to determine the risk of failure in engineering applications. Traditionally fracture mechanics is based on stress intensity factors and J-Integral. However, they are strictly valid under limited applications (for ex., monotonic loading, elastic materials etc.) The needs for fracture for nonlinear materials is sought by several of our customers. Electronics packaging, solders, tires, composites are typical examples. With this in mind, we introduced a novel approach in ANSYS 15.0, viz., Material force. You will find a clear description of the approach in a whitepaper that is available on our websiteContinue reading

Why ANSYS Structural Mechanics 16.0 Is Sweet !

ANSYS 16.0 has some really sweet features for our structural mechanics users. Check out the video below as we use a HexaKopter model from Molly-Shop.De to showcase some key enhancements. Continue reading

What is Mesh Nonlinear Adaptivity?

Many FEA applications can benefit from the ability to strategically modify a mesh during solution, in order to simulate challenging geometry distortions which otherwise cannot be solved. Unlike manual rezoning, mesh nonlinear adaptivity is completely automatic, requiring no user input during solution.

Accelerate Mechanical Solutions with Intel® Xeon Phi™

intel xeon phi coprocessorRegarding high performance computing (HPC), there are numerous improvements introduced into ANSYS Mechanical APDL16.0. However, I would like to focus this post on a feature that demonstrates the technological leadership of our company. ANSYS Mechanical APDL 15.0 was the first commercial FEA software product to support the Intel® Xeon Phi™ coprocessor. In ANSYS Mechanical APDL 16.0, we extend support for Xeon Phi hardware to virtually all users. The Xeon Phi coprocessors can now be used on either Linux or Windows, as well as with shared-memory parallel (SMP) and distributed-memory parallel (DMP). Continue reading

How to Apply a Harmonic Base Excitation Natively in ANSYS Mechanical Workbench 16.0

In a previous post, I have presented how to apply a harmonic base excitation in ANSYS Mechanical 15.0 using three different techniques. Among those techniques, we had the great ACT extension that has received a great attention due to its ease of use and practicality.

ANSYS 16.0 offers the capability of applying a harmonic base excitation natively, and without the need for the ACT. Acceleration applied as a base excitation uses the Enforced Motion Method. Continue reading
