ASSESS Initiative Presents Credible Arguments For Increased Engineering Simulation

Thursday, August 16th, 2018

An innovative organization called ASSESS Initiative LLC was formed by Joe Walsh in mid-2016 for bringing together the key players for guiding and influencing the software development and implementation strategies related to model-based analysis, simulation, and systems engineering, with the primary objective of expanding the use and business benefit of the many forms of engineering simulation.

The changing role of engineering simulation is really about business benefits. However, achieving those benefits and associated growth of the engineering simulation market is tempered due to the lack of understanding regarding its true benefits. According to ASSESS Initiative, a simulation revolution needs to occur that will bring a whole new set of opportunities as well as challenges.

The ASSESS (Analysis, Simulation & Systems Engineering Software Strategies) Initiative is a broad reaching multi-industry initiative with a primary goal to facilitate a revolution of enablement that will vastly increase the availability and utility of Engineering Simulation, leading to significantly increased usage and business benefits across the full spectrum of industries, applications and users. The vision of the ASSESS Initiative is to bring together key players for guiding and influencing the software tool strategies for performing model-based analysis, simulation, and systems engineering. To achieve this vision the ASSESS Initiative will collaborate with multiple activities and organizations across the broad spectrum of engineering simulation.

ASSESS Initiative has been organized around a key set of themes associated with expanding the usage and benefit of engineering simulation that include:

Align – Alignment of Commercial, Research and Government Efforts
Business – Business Challenges
Credibility– Engineering Simulation Credibility

DoES – Democratization of Engineering Simulation
Generative – Generative Design
Integration – Integration of Systems and Detailed Sub-System Simulations

ASSESS Initiative is planning on publishing a series of positioning papers and Strategic Insight papers related to each of these themes.  The positioning papers will be publicly available from the ASSESS Initiative website, however, ASSESS Strategic Insight papers will be made available on a “members only” basis.

As part of this effort, the ASSESS Initiative recently released the first two positioning papers related to its themes above:

Alignment of Commercial, Research and Government Efforts (Align) Positioning Paper

Like a debate, position papers (sometimes called point of view papers) present one side of an arguable opinion about an issue; in this case engineering simulation. The goal of any position paper is to convince the audience that your opinion is valid and defensible. However, it is very important to ensure that you are addressing all sides of the issue and presenting it in a manner that is easy for your audience to understand – not always an easy case with engineering simulation. The biggest job is to take one side of the argument and persuade your audience that you have well-founded knowledge of the topic being presented. It is important to support your argument with evidence to ensure the validity of your claims, as well as to refute the counterclaims to show that you are well informed about both sides. ASSESS has succeeded on all counts with the publication of the first two papers.

The second paper is particularly interesting because the Democratization of Engineering Simulation is implemented in many forms. While there are many common characteristics, issues and opportunities across them all, there are also critical differences that need to be identified and explained, to enable a path to achievable solutions.

The first aspect of any form of implementation of DoES is whether or not it is driven by customers or providers of Engineering Simulation.  The second aspect in any form of implementation of DoES is the type of customer that this form of implementation is intended to be used by (Large Enterprise, Small-Medium Business (SMB), Industry Consortium, mixture of customer types).  The third aspect in any form of implementation of DoES is the “level” of democratization desired, that include:

Product/Project-level democratization – Democratization within a company, at a project level.

Product Development Process-level democratization – Democratization within a company, at a product level; crosses various departments involved in the development of a product; could be distributed globally.

Corporate Enterprise-level democratization – Democratization as a standard practice across an entire enterprise; the company has standardized simulation practices, wishes to enforce them globally, and has committed to putting simulation in the hands of everyone who needs it globally.

Industry-level democratization – Democratization across a particular industry; solution providers create applications that are targeted towards the particular needs of an industry and its products and promote democratization; these applications become widely used across the industry.

The ASSESS Initiative working group related to the Democratization of Engineering Simulation has established the following initial goals for the ASSESS activities related to this theme:

1. Highlight the issues, impediments, and opportunities related to Democratization of Engineering Simulation

2. Advocate for all people who could benefit from using engineering simulation to be able to use it appropriately

3. Advocate for getting engineering simulation safely into the hands of current non-users

4. Advocate for addressing engineering simulation ease of use and required expertise issues that are limiting its broader usage

5. Collaborate with other organizations (e.g. NAFEMS, Revolution in Simulation, …) to support the Democratization of Engineering Simulation

6. Advocate for and support growth in the use of engineering simulation by 10x in 5 years

The paper surmises that the Democratization of Engineering Simulation, not too surprisingly, is likely to require significant changes to current business models for engineering simulation software and computing infrastructures. The current business models for Engineering Simulation software is based on a small number of expert users that run simulations as their primary task. Democratization of Engineering Simulation requires that the use of engineering simulation is broadened to a large number of part-time users with the objective of having more technical personnel being able to make informed design decisions when needed.

This paper reinforces what we have witnessed over the past several years. Namely, engineering simulation being conducted earlier and more often in the product development process by “non-specialists,” such as designers and engineers.

These two papers bring some interesting insights into the present and future direction of engineering simulation on several different levels and I’m looking forward to reading more as they become available.

ANSYS Discovery Live Accelerates Engineering Simulation For Concept Exploration

Thursday, September 7th, 2017

Even though we’ve been told by a number of software vendors for several years now to use engineering simulation and analysis at the earliest stages of product development, relatively few companies have heeded the advice and actually done so. In many cases, it’s still design, break, repeat in a cycle that gets very expensive quickly trying to achieve optimized design goals. Even with all the insistence and chiding from the simulation folks, I’d estimate the percentage of design work that includes simulation early in the process as somewhere between 20-25%, although that may be a bit on the high side.

This week, ANSYS presented a technology preview of what it hopes will break and change that cycle with what it calls ANSYS Discovery Live .

 

With it, engineers can rapidly explore design options and receive accurate simulation results with technology using engineering simulation to make digital exploration available to all engineers so they can design better products faster and more economically.

That’s a pretty confident and heady statement, knowing that several other vendors have attempted the roughly same thing with widely varying degrees of success. However, ANSYS has an interesting and innovative approach for reaching its goal — exploiting GPUs because they can handle massively parallel operations.

ANSYS readily admits that while Discovery Live is a means of bringing simulation to the engineering masses earlier in the development process, it doesn’t pretend to do everything for everybody, and there will always be a place for engineering simulation specialists for deeper dives. Discovery Live is targeted to early design exploration and to users new to simulation. Because it is not a solution for every simulation problem, Discovery Live does not compete with other more advanced ANSYS products, such as AIM, but data from it can be exported for more further study.

Introducing CAE Into Your CAD/CAM Workflow: Look Before You Leap

Friday, January 27th, 2012

There are several types of CAE-related manufacturing applications for optimizing the use of materials, tools, shape and time, and machine layout by simulating and analyzing specific manufacturing processes. However, probably the most common method for getting CAE into a manufacturing environment, finite element analysis (FEA) for parts and tooling.

FEA is a numerical technique for calculating the strength and behavior of structures. It can be used to calculate deflection, stress, vibration, buckling, and other behaviors. Typical applications for FEA would include minimizing weight and/or maximizing the strength of a part or assembly.

In FEA, structures are divided into small, simple units, called elements. While the behavior of individual elements can be described with a relatively simple set of equations, a large set of simultaneous equations are required to describe the behavior of a complex structure. When the equations are solved, the computer and FEA tool displays the physical behavior of the structure based on the individual elements.

FEA tools can be used for innovating or optimizing mechanical designs. Optimization is a process for improving a design that results in the best physical properties for minimum cost. However, optimization using FEA tools can prove difficult, because each design variation takes time to evaluate, making iterative optimization time consuming. On the other hand, FEA tools can really shine when seeking new and unique ways of designing things – the most crucial aspect of innovation.

Before committing to any CAE tool, however, be sure it is compatible with your existing CAD and CAM tools, the types of parts and assemblies you design, and your general workflow.

Keep in mind that there is no one tool that serves everyone’s needs. Some will be interested fluid flow, others in structural mechanical properties, and still others in thermal issues. Get input from as many groups within your organization as are likely to benefit from CAE tools. When evaluating CAE tools, make sure you evaluate them with your models; not just models supplied by a vendor. That way, you’ll be able to objectively evaluate different CAE tools that best suit your needs in your environment, and not be overly swayed by what a vendor wants you to see. Obviously, it’s in your best interest for objectivity to use the same parts or assemblies with different CAE tool vendors.

Finally, a word of caution. Don’t expect CAE tools to solve all your problems with all of your parts. Like CAD and CAM tools, they should be used in conjunction with experience and common sense to arrive at optimized and innovative designs. Calculating return on investment when using CAE tools can be as complicated as performing analyses on complex assemblies. However, you can probably count on estimating ROI from time saved during the design process, lower material costs, reduced numbers of physical prototypes and ECOs, and possibly greatly reducing the number of product liability lawsuits. CAE tools cannot perform miracles by themselves because they still require a significant human element, but employed wisely, will likely improve your workflow and provide tangible benefits.

Introducing CAE Into Your CAD/CAM Workflow: Getting Onboard

Wednesday, January 25th, 2012

By now you’ve almost certainly got MCAD and CAM tools as a vital component of your business. With them you’ve hopefully seen how they have positively impacted the way you work, as well as the way you interact with your customers and vendors. Looking for a way to further increase your productivity, while continuing to optimize your processes?

If you haven’t already, it’s time you considered integrating tools into your workflow for simulation and analysis of virtually any aspect of the product development lifecycle. Although known in some circles as computer-aided engineering (CAE) tools, that acronym has largely been replaced by simulation and analysis, although they all mean roughly the same thing.

It wasn’t all that long ago that CAE was relegated to the latter stages of the design and manufacturing (product development) process — too many times as an afterthought. This is changing, though, on two fronts. First, realizing the potential payback in terms of reduced production time and getting it right the first time, many design and manufacturing organizations have moved CAE tools further forward in the development process. Some are even using them in the earliest stages of design, the conceptual phase. Second, software vendors are getting better at integrating CAE with their CAD and CAM tools.

A major roadblock to CAE’s wider acceptance has been the perception that only high-priced analysis specialists (math PhDs?) could understand and work with CAE tools. While specialists are required for some of the high-end tools for performing complex analyses, there are many CAE tools now on the market that require just some basic training and practice to become proficient in a relatively time.

Admittedly, all CAE tools require a technical mindset, but you don’t necessarily have to have a doctorate in math anymore to run many types of analysis and simulation. It really just requires familiarity with the interface of a CAE tool for creating and loading digital models, and then reviewing and interpreting the results. A really nice thing is that many CAE tools now work from within the familiar UI of your CAD or CAM tool. Finally, computer prices that continue to drop have helped popularize CAE tools, because some of them require a lot computing horsepower when working with large assemblies or very precise engineering constraints.

If this all sounds easy, it is to a point, but there are some caveats. That’s what we’ll discuss next time, as well as the most commonly used CAE tool — FEA.

Altair Engineering’s HyperWorks Technology Conference — Day 1

Thursday, April 29th, 2010

I attend a number of technical and engineering conferences over the course of a year, primarily CAD or CAM related, with some CAE thrown in. Some of the events are good, some are not so good, and some are just a waste of time.

Right now I’m at a very interesting CAE event for the first time– Altair Engineering’s Hyperworks Technology Conference (HTC) 2010. From what I’ve experienced so far, I classify this event in the “good” category.

The event showcases its unique product and service offerings, as well as its diverse user base that represents the automotive, aerospace, defense, consumer electronics, and, medical device industries.

If you are not familiar with Altair Engineering, know that is one of the most significant players in design simulation and analysis with its Hyperworks technology whose product and service capabilities are available on a “pay as you go” basis. The plan is based on tokens purchased and used

As far as the industries represented goes, today’s presentations were slanted a bit toward the automotive industry with talks from Ford, Porsche, Michigan Solar Car customers, and GM, but that’s OK – we are in the Detroit area, after all.

I also spent some time with a couple folks involved with Altair’s industrial design tool, solidThinking. It’s a unique and very capable conceptual design tool that I will be spending hands-on time with over the next few weeks as the new version, 8.1, is due to ship in the near future.

This blog post provides just a brief overview of the conference, but I’ll be going into more detail on specifics of what I experienced and who I talked to in the next MCAD Weekly that publishes May 10, 2010.
