  • MCADCafe Blog: ASSESS Initiative Presents Credible Arguments For Increased Engineering Simulation

    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 Summary

    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.”

  • Model-Based Systems Engineering for Aircraft Engines

    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 Summary

    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.

  • The Democratization of Simulation with Intelligent Templates

    CIMdata report of a 2012 presentation by Malcolm Panthaki on the use and benefits of Intelligent Templates to Democratize Simulation.

    View Summary

    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.

    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 paper was published in the 2014 Conference Proceedings of the SPIE.

  • Using (Simulation) Templates to Support The Engineering Designer

    ASME paper on simulation templates for designers.

    View Summary

    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

  • Engineering Design Platforms and Simulation in-CAD Benefit Product Development Teams

    Computer-aided engineering (CAE) tools have the power to take the gut feel and rules of thumb out of the engineering world.

    View Summary

    Customers want cheaper, lighter, faster and stronger products that work the first time. Oh, and while you’re at it, those products must look cool, too.

    To meet these demands, engineers must bring simulation early into the development cycle to drive innovation.

    To that end, tools like simulation in-CAD (computer-aided design) and engineering design platforms make it easier for designers and design engineers to quickly check their work and make informed decisions about how their innovative ideas will affect product performance.

  • On Democratizing Technology: How hard can it be to set the clock?

    CIMdata’s Executive Consultant, Dr. Keith Meintjes, recently shared his views on the need to democratize technology so that it is easy for the end-user.

    View Summary

    “I think this is quite an important issue, the need to democratize technology so the interface is easy and intuitive (or even automatic) for the end-user. This goes directly, I think, to the question of the usability of software and technology. It is ridiculous, in my mind, that you have to master an electronic user manual or watch a five-minute video to adjust the clock by 18 minutes.”
