PTC's Gregory Brown writes that simulation is no longer entirely the preserve of degreed specialists, and is evolving to serve a broader audience.View SummaryGet Content
Simulation has evolved to the point where it should be part of every designer’s workflow. When you send your design for formal analysis, you’ll know you’re sending a more developed product to the analysis department—not asking them to figure out if the bolt has the wrong diameter.
Here’s a quote from the article:
Looking back a couple of decades, it was really only the big aerospace and automotive companies that got the most value out of simulation, or even attempted it. That’s no longer true. Now, every organization—and the design engineers in those organizations—can get value and should be using it. You’re missing out if you don’t, and even more so when your competitors do!
Practice makes perfect may be a cliché, yet the agile and time-to-market benefits of simulation in manufacturing are too great to ignore.View SummaryGet Content

Jeff Rowe of MCADCafe posts a blog on MCADCafe Newsletter about the ASSESS Initiative Positioning Papers regarding Democratization of Engineering Simulation (DoES) and Aligning Commercial, Government, and Research Engineering Simulation Efforts.View SummaryGet Content
Jeff Rowe comments:
“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 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.
. . .
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.”

P&G determined that software modeling tools are critical for the kind of innovation necessary to develop thousands of consumer products competitively, and has therefore invested heavily in a variety of modeling and simulation technologies. Realizing that the benefits of modeling and simulation could be scaled by orders of magnitude if only these tools could be made usable by a much wider and larger group, P&G turned to EASA to help democratize modeling tools as intuitive streamlined web apps.
Previously limited to specialists, many tools (and related workflows) such as spreadsheets, legacy codes, databases and CAE applications were quickly repackaged as EASA web apps, which offer:
• Ease of use, built in intelligence, consistent look-and-feel, and error-checking
• Ease of access, running with complete reliability (even on mobile devices), with no dependence on locally installed software
• Intellectual property security and audit trail of usage
With EASA, Air International has leveraged the benefits of simulation and modeling by creating custom, task-specific web apps simplifying the use of many CAE workflows, including tools such as Fluent, NX/NASTRAN, and CATIA. Furthermore, expert knowledge was embedded into the streamlined user interface, making modeling and simulation available to engineers and designers with little or no CAE experience while also significantly accelerating the process for experienced users.
In addition to significant ease of use improvements, Air International benefited from many other EASA advantages, including:
The problem of legacy applications
Over the past four decades, IT staff at Monsanto have developed many custom applications to help the firm’s managers, engineers, and plant operators to solve problems specific to the business. However, these applications were developed in the days of DOS; being command line driven, they were very difficult to use, especially for younger employees accustomed to more modern graphical user interfaces.

Modelon’s newest library, the Jet Propulsion Library, provides the foundation for modeling and simulating jet engines along with the integrated model-based systems engineering of aircraft systems.View SummaryGet Content
The prime mover of an aircraft, the jet engine, is one of the most important subsystems of an aircraft. Jet engines provide primary power (thrust) and secondary power (to drive flight control, air conditioning, cabin lighting, etc.) to the aircraft. Performance and efficiency improvements are becoming increasingly difficult to achieve when focusing on the engine in isolation. In the past, engine improvements have largely been developed separately in incremental design cycles – these cycles have not considered the need to develop the total aircraft package as an entire unit. Today, aeronautical systems and their subsystems are becoming more and more integrated and therefore simulation models need to become further aligned to meet performance and efficiency needs.View Blog Post

The arrival of the Functional-Mockup-Interface (FMI) has been a game changer by simplifying the combination of models from different tools.View SummaryGet Content
Most of us know by now that there is not one single software tool that will solve all our simulation needs. Even if we narrow it down to system simulation, we will not find that One tool.
Not so long ago, handling different aspects of product design with separate tools was not a major problem. But as competitive pressure builds to get products to market faster, the game is changing.
A major key to success is being able to integrate subsystems into system simulations early in the design process. This enables organizations to understand and assess system behavior, as opposed to component or subsystem behavior, to avoid flaws that become costly to correct in later stages.View Article

The Democratization of Simulation with Intelligent Templates
Realizing the Full Benefits of Simulation
An “Intelligent Template” is an innovative concept in product development that focuses on the automation of simulation processes across a product family. The template leverages the common functional architecture across the product family using a concept called the Abstract Model. This functional model of the product family is independent of a particular instance of the product design and of its geometry. The template captures the simulation best practices of the organization and enforces them when it is executed on a particular instance of the product design.
Experts must create the templates, but non-experts can use them reliably.View ArticleDownload

Structural-Thermal-Optical-Performance (STOP) Model Development and Analysis of a Field-widened Michelson Interferometer
An integrated Structural-Thermal-Optical-Performance (STOP) model was developed for a field-widened Michelson interferometer which is being built and tested for the High Spectral Resolution Lidar (HSRL) project at NASA Langley Research Center (LaRC). The performance of the interferometer is highly sensitive to thermal expansion, changes in refractive index with temperature, temperature gradients, and deformation due to mounting stresses. Hand calculations can only predict system performance for uniform temperature changes. An integrated STOP Simulation Template was developed to automate and investigate the effects of design modifications on the performance of the interferometer in detail, including CTE mismatch, and other three- dimensional effects.
The STOP Template was developed using the Comet SimApp Authoring Workspace which performs automated integration between Pro-Engineer®, Thermal Desktop®, MSC Nastran™, SigFit™, Code V™, and MATLAB®. This is the first flight project for which LaRC has utilized Comet, and it allows a larger trade space to be studied in a shorter time than would be possible in a traditional STOP analysis. This paper describes the development of the STOP Template, presents a comparison of STOP results for simple cases with hand calculations, and presents results of the correlation effort to bench-top testing of the interferometer. A trade study conducted with the STOP model which demonstrates a few simple design changes that can improve the performance seen in the lab is also presented.

This ASME paper, “Using Templates To Support The Engineering Designer Performing Computer-Based Design Analysis”, authored by Hakan Petersson, discussed how simulation templates can be used by engineering (CAD) designers to perform complex simulations.
Here is an extract from the Abstract:
The introduction of TBDA in an industrial setting has resulted in many advantages, such as shorter lead times, opportunities to generate more concept candidates, and increased collaboration between the engineering designers and the design analysts, all of them contributing to more mature technical solutions. Three different automation levels of TBDA have also been identified and accounted for as well as being exemplified. In the companies in which TBDA has not been implemented, some of the reasons for not doing so are high costs, company policy, and the lack of knowledge and experience on the part of the engineering designer. This paper presents the results both from the new online survey as well as from the interviews. © 2015 by ASME

Whitepaper by Chad Jackson, analyst, researcher and blogger with Lifecycle InsightsView SummaryGet Content
In today’s design environment, it’s increasingly necessary to combine multiple file types in a single project. If you need to work with parametric, direct and facet modeling within the same project, some CAD platforms require you to move design data across multiple pieces of software.
However, there are CAD systems that integrate parametric, direct and facet modeling into one work environment, saving time and ensuring that no data is lost, regardless of the type of design work you’re performing.
In this 10-page whitepaper, you will learn:
