Simulation Powering Destination Zero

Bob Tickel - Cummins - Keynote Speaker at NAFEMS World Congress 2023

Bob Tickel


The automotive, transportation, off-highway and power generation industries are aggressively pursuing zero/near-zero emissions products. As a power provider for a vast array of markets, regions, customers, etc., Cummins must be positioned to provide the right powertrain at the right time for the specific needs of a diverse set of customers and applications. These needs will be evolving with time and even be specific to a particular customer duty cycle and location in the world.

Given a “well-to-wheels” (WTW) focus on decarbonization, the source of the fuel or energy pathway must be factored into the unique powertrain solution being provided to a customer. While zero carbon emissions may be achieved at a machine level, the source of energy will potentially drive carbon emissions in the wrong direction given a WTW view. For example, a specific mining site will have unique pathways for different fuels or electricity each having a varying cost and carbon footprint. This will drive unique infrastructure and powertrain solutions that considers the trade-off between TCO and carbon emissions over time. Cummins must have technological diversity for powertrains along with tools that help customers make the best decisions to hit their success business, environmental, etc. goals.

Modeling and simulation have been key enablers for the success of Cummins and its customers in the past and will play an even more important role moving into the future. Additional capability, along with the depth already in place, is required in terms of skills, tools, and processes for all potential technologies. Managing complexity, improving engineering efficiency, increasing agility, and ensuring complementary physical measurements are all key for Cummins to excel and modeling and simulation will be central to them all

The Science and Mission of the James Webb Space Telescope

Michael Menzel - NASA - Keynote Speaker at NAFEMS World Congress 2023

Michael T. Menzel

JWST Mission Systems Engineer


The James Webb Space Telescope (JWST), launched on December 25, 2021, is NASA’s successor mission to the Hubble Space Telescope. JWST has been designed and developed to observe “first light” objects in the nascent universe, the evolution of galaxies over cosmic history, star birth within our own galaxy, planet formation and evolution both in our solar system and in solar systems around other stars and to make detailed observations of some of the recently discovered exoplanets. The JWST telescope has an aperture greater than 6 meters in diameter, and along with its compliment of science instruments must be cooled to cryogenic temperatures below 50K. It will be operated at the Sun-Earth L2 point to keep thermal sources such as the Sun and Earth in the same general direction so that their radiation can be shielded by a “tennis court sized” sunshield, allowing the payload to attain these temperatures passively.

This presentation will give an overview of the JWST science and its systems design challenges, and discuss the lessons learned from this mission.

Michael T. Menzel has 41 years of experience in the aerospace, working 23 years in industry for commercial and defense missions and for NASA for the past 18 years. He is currently the Mission Systems Engineer for the James Webb Space Telescope.

Mr. Menzel received a B.S. in Physics from the Massachusetts Institute of Technology in 1981 and an M.S. in Physics from Columbia University in 1986. He began his career in 1981 with the RCA Astro Space Division in East Windsor, N.J. as an antenna engineer, designing flight antennas for commercial and defense communications and remote sensing satellites. In 1990 he took a position in the Systems Engineering Group of the General Electric Astro Space Division designing commercial, DOD and civil space systems. In 1995 he took a position as Director of Systems Engineering in the Orbital Sciences Corporation, and in 1997 he took a position as the Deputy Program Manager for the Hubble Space Telescope Servicing Group at Lockheed Martin.

Mr. Menzel began working on the Pre-Phase studies for the Next Generation Space Telescope in 1998, and in June of 2004 he took the position as the NASA Mission Systems Engineer for the James Webb Space Telescope.

Digital Transformation of System Performance Development by a Flexible Digital Thread

Ernesto Mottola - Toyota Motor Europe - Keynote Speaker at NAFEMS World Congress 2023

Ernesto Mottola

Senior Manager - Strategy Planning and Digitalisation

Toyota Motor Europe

Automotive industry challenges with new CASE requirements and the need for an integrated development approach.

Automotive development needs to satisfy an ever-increasing number of conflicting requirements in a market quickly evolving by demand for CASE (Connected Autonomous Shared Electrified). Specialists from different engineering backgrounds have traditionally dealt with this using standardised methods developed in each domain over the years, but they are now faced with the challenges arising from the increasing complexity of products and services, which become more and more integrated in a system of systems environment.

On the one hand, we face the need to shorten development lead time to catch these trends and to respond to the competition from new entrants to the market. On the other hand, we need to facilitate collaboration among the engineers involved in the development of mechatronics systems with increasing functions and interfaces.


Toyota Motor Europe (TME) approach

Toyota Production System (TPS) as a driver for digital transformation

Toyota’s philosophy to continuously improve working processes towards quality and efficiency traditionally comes from manufacturing and is based on the principles of automation and “just in time”.Those principles, widely known as the “Toyota Production System”, apply perfectly as drivers for digital transformation and improving collaboration.

Toyota Motor Europe has been implementing digital transformation initiatives based on those principles, starting with Model Based Development (MBD), which envisions the holistic development of the vehicle and its subsystems by the coherent application of simulation.

The flexible digital thread as a foundation for digital transformation.

The “continuous” nature of the TPS approach demands that the foundation for digital transformation should be flexible enough to support process improvements which are never finished. TME has developed an approach where data can be managed flexibly enough to grow the scope of digital processes, and the related parties that can benefit from it.

TME use cases, from EDM to SPDM, towards simulation supported effective development.

In the past, we have shown example cases of engineering data management and automated generation of simulation models for system performance development; in this presentation, we provide an overview of the vision and the latest updates on how the same foundation supports the implementation of a system centric simulation process, data management, and ultimately improving the effectiveness of simulation-based performance development.

Ernesto Mottola is an engineering manager with a PhD background in structural mechanics and CAE, and a relevant track record in digitalisation. He leads a multicultural team of talented professionals in charge of analysing and designing the development processes of tomorrow, optimising resources, and supporting the transition of TME from a vehicle manufacturing company to a mobility company.

Our mission:

  • Engage with R&D stakeholders to understand their working practices and needs, identify prioritised improvement areas and potential for synergies
  • Continuously develop and deploy innovative digital solutions to eliminate low-value jobs and increase quality, based on Toyota Production System principles
  • Align the engineering organization along a common vision and technical strategy.
