Simulation Automation (Templates)

Simulation Automation is critical to achieve the Democratization of Simulation

Do you wish to Automate your Simulation Processes?

Simulation Automation using templates has been used by many organizations to significantly improve the accuracy, consistency, repeatability, and efficiency of performing complex simulations.  For example, the use of SimApps – simple-to-use Apps that drive underlying Simulation Automation Templates – has put the power of simulation in the hands of non-experts in many product development organizations. Web-Deploying these SimApps provides ubiquitous access to them, often across global organizations, ensuring that best practices are not just documented, but enforced via executable templates.

  • 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.

    Experts must create the templates, but non-experts can use them reliably.

    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

    Solution Providers:

    View Summary

    The long desired goal of simulation driven design has been to enable engineering analysts to focus on achieving the product’s functional requirements starting early in the R&D cycle. By putting simulation analysts in control of the “engineering geometry” starting at the conceptual design stage, reusing CAE best practices, and automating highly manual and repetitive

    design simulation tasks, performance simulation results can finally drive critical new product development decisions.

    As Dr. David Thomas (Engineering Team Lead, The Aerospace Corporation) commented, “The Comet-enabled integrated STOP process allowed our interdisciplinary engineering team to conduct an analysis that normally takes several days or weeks to perform to be completed in a single day. These savings are realized for each design cycle in the iterative process needed to converge to a satisfactory overall design for the IR telescope.”

    View Summary

    A Structural-Thermal-Optical-Performance (STOP) analysis is an interdisciplinary analysis used to verify optical requirements. It is performed to identify and solve design issues early before building hardware. In a traditional STOP analysis, data must flow sequentially from engineer to engineer, requiring multiple data handoffs, which are time-consuming. If the STOP analysis shows that design changes are necessary, trade studies can also be time-consuming.

  • Multiphysics for the masses. COMSOL wants to democratize simulation in the design process– TV-report

    Simulation is key to making virtual product development a reality. So it's no wonder that simulation software is growing rapidly in terms of software spending and usage in product development processes.

    View Summary

    The Simulation and Analysis piece of the PLM investment pie was 12.3% in 2013, making it almost as big as the cPDM component at 13.8%.  While a few big providers lead the CAE market, there are still major opportunities for other market participants including COMSOL, a developer of multiphysics solutions. Over the last five years or so they have seen their revenues increase by 20% per year to around $65 million 2013. This makes them one of the market leaders in the multiphysics CAE sub-segment.

  • GDLS Achieves Early Simulation using Simulation Automation Platform

    In this 2008 case study whitepaper, Bruce Jenkins interviews senior engineer Mike Patterson at General Dynamics Land Systems, about their use of the Comet simulation automation and Abstract Modeling technology to bring simulation upfront.

    Solution Providers:

    View Summary

    How to bring simulation earlier in the product design process has been discussed for years but few have been able to overcome the technical and work-process barriers to doing so. General Dynamics Land Systems (GDLS) has launched a process where automation through templates with abstract modeling technology creates a seamless modeling/simulation process. By eliminating manual steps and allowing engineering and analysis processes to be built around an abstract model, this new process condenses project timelines – in a project piloting the new technology, extracting data from a CAD model and using it to populate an analysis database was slashed from an all-day job to just two hours. Even more, the new process makes it feasible to begin analysis early in design, while alternative geometries and product configurations are still being evaluated.

    Mike Patterson emphasizes how this rapid-response capability (based on Comet’s automation platform) promises to transform the role of simulation and analysis in product development, radically increasing the value it offers to a program. “We want to change analysis from a reactive process occurring late in development, to a proactive process used early and throughout design.”
