Getting to Know PADT: ANSYS Sales and Support

This post is the eighth installment in our review of all the different products and services PADT offers our customers. As we add more, they will be available here.  As always, if you have any questions don’t hesitate to reach out to info@padtinc.com or give us a call at 1-800-293-PADT.

When we tell people that “We Make Innovation Work” one of the key ways that we actually make innovation work is through the sales and support of ANSYS Simulation Software.  Few toolsets have changed the way products are designed and manufactured as the structural, thermal, fluid, electromagnetic, and multiphysics simulation programs written by ANSYS, Inc. Outside of the world of mechanical engineering, simulation is not as well known as 3D Printing, but in reality, it plays a larger role in product development with more users and a larger return on investment to companies that make simulation part of their process.

If you are not familiar with simulation, it is a process where a mathematical model is constructed on a computer to represent the physical behavior of a product. Once the model is made, an engineer can do “virtual testing” on the model to understand, improve and optimize the design.  The majority of innovative companies now make simulation a part of their product development process, and ANSYS is the largest provider of simulation tools.

Customers choose ANSYS products for one simple reason, they deliver.  ANSYS only does simulation, they are not a CAD or PLM company trying to add simulation.  With close to $1 Billion in sales, and 2017 should cross that threshold, no other provider is as large either.  They are the biggest provider because their software works. Many other companies offer much cheaper solutions, but time after time companies invest in ANSYS technology because they get their money back quickly in better products that get to market faster.

PADT is not just a reseller of software, we are an ANSYS Elite Channel Partner who dedicates a significant part of our staff, over twenty people, to selling, supporting, and training around the complete ANSYS Product line.  Our territory is the Southwestern United States; including Arizona, New Mexico, Colorado, Utah, Nevada, and Southern California. We have been setting the standard for win-win sales and outstanding support for over twenty years and have a worldwide reputation for technical excellence not just with ANSYS tools, but in how to efficiently use those tools to drive the design of products.

Our sales process starts with understanding our customer’s complete simulation needs; what they have now, what the skill set is of their users, and what they want to achieve with simulation. We then work cooperatively with the customer to design a long-term plan to bring the right ANSYS tools to the right users and to train as needed.   Once a company adds the ANSYS tools, they then have PADT to call directly for technical support.

Our technical support is unique in the industry because it goes beyond the installation and error tracking that most software companies provide. When you call PADT for technical support you get an Engineer with real-world experience using the same tools you use every day. They also know engineering and how simulation fits into the process so we can go beyond what options to use and dig deep into how to apply the products properly. Our outstanding technical support is reflected in our extremely high customer satisfaction rating.

You can learn more about ANSYS by visiting that part of our website, or better, by contacting us and learning why customers who have a choice on who they buy their ANSYS from, chose PADT.

 

 

Save, Save, Save! Setting up a Save after Solution in ANSYS Mechanical

NOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!

Is this the reaction you have when you come in on Monday morning, and realize that another Windows update has, once again, rebooted your PC before you had a chance to save the 30-hour run that should have finished over the weekend? There a Workbench setting that can help relieve some of that stress.

The “Save Project After Solution” option will save the entire project as soon as the solution has finished. So when your model runs for 30 hours over the weekend, it gets saved before a Windows update shuts everything down.  These settings are persistent, so once you’ve changed them to ‘Yes’, then you are all set for next time. You just need to make sure that you change them for each ANSYS version if you have more than one installed.

Now on to my next blog… “How to recover a run if you forgot to change the settings above.” (Grumble Grumble!)

Transitioning to ANSYS

Before joining PADT last July, I have worked on FEA and CFD analyses but my exposure to ANSYS was limited and I was concerned about the transition. To my delight, the software was very easy to learn; most often than not intuitive and self-explanatory (e.g. mechanical wizard), the setup time was minimized after learning couple simple features (e.g. named selection, object generator etc.) and the resources on the ANSYS portal were very instrumental in the learning process. Furthermore, the colleagues at PADT proved to be very knowledgeable and experienced and more importantly responsive and eager to jump for help.

One of the most attractive features that caught my attention was the streamline of the Multiphysics nature that ANSYS has. I have been satisfied with the performance of standalone CFD packages in the past, and same goes for structural ones. But never have I dealt with an extensive software that maintained the quality of a specialized one. The importance of this attribute is showing more and more its powers in recent years given the development of new convoluted products of Multiphysics nature e.g. medical applications.

Using ANSYS to simulate medical applications is one of the most rewarding experience I personally enjoy. Even though, it is definitely satisfying to be able to help accelerate innovation in the aerospace, automotive, and a myriad of other industrial areas…the experience in the medical area has a more refreshing taste, probably due to the clear and direct link to human lives. From intravascular procedures to shoulder implants and microdevices, there is one common factor: ANSYS is decreasing the risks of catastrophic failures, improving the product capabilities and shortening the innovation cycle.

Editors Note: Ziad is part of PADT’s team in Southern California.   He is a graduate of USC and has worked at Boeing, Meggit, and Pacific Consolidated Industries before joining PADT.  He works with the rest of our ANSYS technical staff to make sure our users are getting the most from their ANSYS investment.

IEEE Day 2017: Smart Antennas for IoT and 5G

IEEE Day celebrates the first time in history when engineers worldwide and IEEE members gathered to share their technical ideas in 1884. Events were held around the world by 846 IEEE Chapters this year. So, to celebrate, I attended a joint chapter meeting in at The Museum of Flight in Seattle with technical presentations focused on “Smart Antennas for IoT and 5G”. There were approximately 60 in attendance, so assuming this was the average attendance globally results in over 50,000 engineers celebrating IEEE Day worldwide!

The Seattle seminar featured three speakers that spanned theory, design, test, integration, and application of smart antennas. There was much discussion about the complexity and challenges of meeting the ambitious goals of 5G, which extend beyond mobile broadband data access. Some key objectives of 5G are to increase capacity, increase data rates, reduce latency, increase availability, and improve spectral and energy efficiency by 2020. A critical technology behind achieving these goals is beamforming antenna arrays, which were at the forefront of each presentation.

Anil Kumar from Boeing focused on the application of mmWave technology on aircraft. Test data was used to analyze EM radiation leakage through coated and uncoated aircraft windows. However, since existing regulations don’t consider the increased path loss associated with such high frequencies, the integration of 5G wireless applications may be restricted or delayed. Beyond this regulatory challenge, Anil discussed how multipath reflectors and absorbers will present significant challenges to successful integration inside the cabin. Although testing is always required for validation, designing the layout of the onboard transceivers may be impractical to optimize without an asymptotic EM simulation tool that can account for creeping waves, diffraction, and multi-bounce.

Considering the test and measurement perspective, Jari Vikstedt from ETS-Lindgren focused on the challenges of testing smart antenna systems. Smart or adaptive antenna systems will not likely perform the same in an anechoic chamber test as they would in real systems. Of particular difficulty, radiation null placement is just as critical as beam placement. This poses a difficult challenge to the number and location of probes in a test environment. Not only would a large number of probes become impractical, there is significant shadowing at mmWave frequencies which can negatively impact the measurement. Furthermore, compact ranges can significantly impact testing and line of sight measurements become particularly challenging. While not a purely test-oriented observation, this lead to considering the challenge of tower hand off. If a handset and tower use beamforming to maintain a link, if is difficult for an approaching tower to even sense the handset to negotiate the hand-off.

In contrast, if the handset was continuously scanning, the approaching tower could be sensed to negotiate the hand-off before the link is jeopardized.

The keynote speaker, who also traveled from Phoenix to Seattle, was ASU Professor Dr. Constantine Balanis. Dr. Balanis opened his presentation by making a distinction between conventional “dumb antennas” and “smart antennas”. In reality, there are no smart antennas, but instead smart antenna systems. This is a critical point from an engineering perspective since it highlights the complexity and challenge of designing modern communication systems. The focus of his presentation was using an adaptive system to steer null points in addition to the beam in an antenna array using a least mean square (LMS) algorithm. He began with a simple linear patch array with fixed uniform amplitude weights, since an analytic solution was practical and could be used to validate a simulation setup. However, once the simulation results were verified for confidence, designing a more complex array with weighted amplitudes accompanying the element phase shift was only practical through simulation. While beam steering will create a device centric system by targeting individual users on massive multiple input multiple output (MIMO) networks, null steering can improve efficiency by minimizing interference to other devices.

Whether spatial processing is truly the “last frontier in the battle for cellular system capacity”, 5G technology will most certainly usher in a new era of high capacity, high speed, efficient, and ubiquitous means of communication.
