Abstract: openSPDM on the Aras Platform

Simulation Process & Data Management is an application pioneered by high performance Automotive and Aerospace OEMs and Tier 1 suppliers to build and maintain the Digital Thread of the data used and the decisions taken to predict the performance and lifetime of engineered products. The records in an SPDM solution enable these companies to rapidly stand up a functional Digital Twin of an actual product to support manufacturing or operations. Today many SPDM solutions were built from scratch by internal IT teams and are in need of replacement. SPDM uses graph structures to build and maintain the Digital Thread. This presentation will provide an analysis of the platform capabilities required for an SPDM solution and share the reasons I selected Aras as the platform for openSPDM.

Companies face unprecedented pressures to improve Product Performance▫ Environmental Pressure for fuel economy and emissions▫ Regulatory Pressure for Safety, passenger and pedestrian▫ Competitive Pressure; Performance, Cost, Quality, Features

Companies are turning to Simulation Based Development to achieve these improvements due to▫ Accuracy of simulation results▫ Speed of Iteration▫ Cost per Iteration▫ Information available from a simulation▫ Flexibility to investigate alternatives and combinations

Companies need to increase Simulation Capacity▫ Empower analysts to achieve greater throughput▫ Access distant/exterior resources▫ Democratise analysis to a wider population

Thermodynamic efficiency▫ Asymptotic to ideal performance

System Simulation▫ Improvements now require system‐level simulations, multi‐disciplines

Leading to the requirement to do ▫ more simulations, iterative simulation▫ more sophisticated simulations ▫ more system level simulations▫ simulations with development partners

More & more data, more complex simulation data sets▫Manual data management is no longer sufficient

The scale of engineering simulation today

An Automotive OEM uses 20,000 cores for engineering simulation

Creates 5‐10 Petabytes of Simulation Data yearly

Create 90,000,000 data/metadata objects yearly

Analysis team is only a few hundred engineers

Quality & Traceability

IP & Knowledge Base

SDM is a specific xDM data management technology that can be deployed to accelerate processes,

enable global simulation teams, ensure quality & traceability,

capture IP and build a Knowledge Base

openSPDM

Why Early Adopters implemented SDM:

Traceability to assure simulation quality ‐ Digital Thread▫ Safety▫ Regulatory Compliance▫ Formal Justification of Business Decisions

To support a new ways of working▫ Granular simulation data sets for Optimisation/Design Space Exploration, Robust Design

Reduction of Data Management Overhead on Analysts – Increase productivity▫ Increasing number of files in a dataset▫ Increasing number of analysis iterations

Information Lifecycle Management

Formalisation of process automation▫ Scripts under version control

• 2 year study through the NAFEMS Simulation Data Management Working Group

• Interviews and workshops with – Ten OEMs– Three Tier 1 suppliers

• Analysis and summary of papers from NAFEMS & CPDA conferences

• Extensive peer review

There is a clear opportunity to decrease % of time spent on non-technical work and hence increase throughput with SDM

But SPDM adoption is very low

SDM has very limited adoption by the 750,000 analysts worldwide, only 1 to 2% of engineering analystsWhereas PDM or PLM adoption is now 90%+ in any industrial company using simulation Information system deployment & usage is new for Modelling & Simulation organisationsMost Analysts still use the file system & logbook/powerpointDigital Transformation like SDM and PLM is difficult, especially the first timeCost & Budget are issues ‐ a POC can cost €50k ‐ €250k

Why openSPDM, the SPDM challenge

“COTS” SDM in production since 2000 at BMW, today 2,000,000 vehicle simulation data‐sets are managed in their SDM system; assuring quality, providing traceability + large throughput gains

The uptake of SDM across all industry sectors has been very slow compared to PLM. Of 750,000 simulation engineers worldwide, perhaps 15,000 use SDM,2%

Education & mastery of SDM is limited so deployment resources are scarce▫Training available from NAFEMS.org

A few capable SPDM solutions, expensive, finite scope, .

M&S organisations have no experience of Digital Transformation, no budget for SPDM

Poor image of SDM from failed deployments of not‐fit‐for‐their‐purpose solutions

No open‐source SDM solutions yet, so analysts cannot experiment or try before buy

openSPDM

openSPDM approach

openSPDM will lever the highly functional Aras Innovator xDM platform to deliver core SDM functionality as open‐source▫Open to all CAE Applications, Solvers, Toolsets eg viewers▫Configurable, by the Methods team ▫Extensible▫Accessible as no up front licence feeOpen‐source extensibility enables application and domain‐specific extensions▫by Aras, third party vendors, service providers, in‐house teams ▫Opportunity for an open‐source community to contribute

openSPDM

©theSDMconsultancy

openSPDM will enable wide SPDM adoption

openSPDM will be used in SDM education to enable students to interact with core SDM functionality and truly understand what SDM is about

openSPDM will enable Proofs of Concept and Pilot deployments

openSPDM open source community will offer application and solver integrations, specific extensions for particular domains

Production deployments of openSPDM will benefit from wider Aras functional capabilities such as CAD data management, MS Office integration, Change Management, Document Management, Quality Management, Enterprise Search,…

Production deployments can benefit from Maintenance, Enhancement, Support and Upgrades from Aras Corp (Red Hat model) + value added SDM modules

openSPDM will deliver Digital Thread & Digital Twins in ARAS PLM deployments
