Training Help

�� Development continues in the most mature branch—environments and solvers (“But how much is used?”) �� Nonlinear, non-”standard” materials, materials design, multi-physics, multi-

fidelity, multi-scale,…

�� More attention to the “connectors” (the keys to synergy): �� Training and help: In-line and on-line �� Simulation Process Management (SPM): capturing,

standardizing, and re-using best practices, linking multiple software tools; “Intelligent Templates”

�� Knowledge-based Engineering (KBE): leveraging past work on similar new projects, accessing past expertise and relevant data; “Intelligent Templates”

�� Simulation Data Management (SDM): �� storing, retrieving, and re-using results of simulation runs �� Recognizing the differences between PDM and SDM:

temporary storage of significant (size of files) results vs. archiving end results

Overview of Key Trends in Engineering Simulation (1)

Overview of Key Trends in Engineering Simulation (2)

�� Significant growth of materials research, data, use (Multi-scale) �� Composites, micro- and nano-materials, simulated materials testing,…

�� Multi-physics: different physical phenomena interacting/affecting each other, e.g., �� Structural-thermal �� Fluid-structure interaction (FSI) �� CFD with chemical reactions, combustion �� Structural, CFD, electromagnetics

�� Multi-fidelity/System Level (model/network-based): �� Structural: 1-D (bars, beams), 2-D (plates, shells), 3-D (solids) �� Flow: 1-D (piping networks, 3-D CFD (single-phase), 3-D CFD (multiphase) �� Block-diagrammatic system modeling (MatLab, SABER, SysML, Modelica,

LabVIEW,…), connecting to 3D �� Simulation Governance (SimGov):

�� administering enterprise-wide use of simulation as a corporate asset �� “Command and Control”

Key Near-Future CAE Trend Themes

�� Simulation-driven design (SDD) �� Democratization (supply meets demand) �� “The Cloud” (ubiquitous computing access) �� Multi: Scale/Level, Fidelity, Physics �� Mechatronics Convergence (MCAE meets ECAE/EDA �

CAE) and beyond to requirements capture, systems modeling and simulation (MBSE)

�� Continual Evolving ISV Ecosystems (acquisition, creation)

�� Simulation Governance

All of these are a mixture of business and technology trends

Simulation before Traditional CAD

�� Using simulation (CAE) to drive product development and more detailed product design features, rather than following that step as a “verification” step.

�� “De-featuring” tools are proof that the CAD process has gotten ahead of where it should be (?)

�� SpaceClaim, as an example, has targeted this pre-CAD segment/need

�� Berlin-based FRIENDSHIP SYSTEMS (a DNV-GL company) also sees the advantage: �� “Traditional CAD tools (e.g. CATIA, NX, Pro/E, SolidWorks),

although powerful, are detail-oriented and encompass features which may not be relevant for simulation.”

--FRIENDSHIP Framework web page

The Famous “V” Diagram (Should it be a “W”?)

Dramatic Potential Expansion of Simulation Use

Population of product development engineers who could make use of simulation Population of simulation

engineers capable of using today’s generation of CAE tools

Widening the Availability of Simulation to “Design” Engineers (“Democratization”?)

�� “Old” Paradigm: A CAD company purchases an FEA/CFD tool/company and offers a CAD-embedded version of the traditional analysis process. �� Examples: PTC�Rasna, Solidworks�SRAC (Cosmos), Autodesk� Algor,

PlassoTech, Siemens PLM�Femap �� Vince Adams wrote recently (in DE article): “Autodesk wasn’t prepared to

accept the status quo. Per Scott Reese, the company’s senior director of Simulation Solutions, after exhaustive research with customers and across the market, Autodesk chose a different approach that it expects to be a game changer…”

�� “Newer” Paradigms: �� Creating simulation tools/wizards/e-handbooks to give non-simulation-experts

reliable answers to specific classes of difficult (simulation-dependent) problems using simulation “under the covers.”

�� “Intelligent” templates for capturing, driving use of “right” simulation at the right stage of product development (= at the right positions on the “V” diagram)

Current Expertise Requirements

How to close this gap?

A Few Examples of Wizards & Templates

“Intelligent” Templates (COMET Solutions)

“The Cloud” �� A lot of talk (hype?), increasing availability of remote

computing access, called “Cloud” by individual vendors �� This is the subject of a whole different presentation �� But still to early to predict which business model(s) will

emerge and dominate �� Client-server, web/browser portals

�� Cloud-based simulation has some additional layers of difficulty: �� the need to more automatically locate enough powerful

computing (clusters/nodes/cores) to get the job done as fast as possible

�� Software pricing/licensing models for “pay as you go” �� Remote visualization of results vs. downloading very large

files for local visualization �� …

“Aha!” (Insight)

TheUberCloud HPC Experiment: An open voluntary collaborative community Objective: Making HPC as a Service available, for everybody, on demand How? For SMEs and their engineering applications to explore the end-to-end process of using remote computing resources, as a service, on demand, at your finger tips, and learning how to resolve the roadblocks.

UberCloud Poll about Roadblocks

Trends in Broader MCAE Environments

�� The ongoing debate of “integrated, from a single supplier” vs. “best of breed” from multiple vendors continues to this day because, in reality, end users and end-user companies really need a common environment where seamless integration of best of breed is available.

�� Vendors of solver tools and environments focused/oriented mainly around their own tools are opening up to the heterogeneous tools needs that will remain for the foreseeable future. �� From captive environments to open foundations/

frameworks

“Best of Breed” Vendors in Main MCAE Application Areas

�� Flexible mechanics (structural) solvers (FEA): �� ANSYS, MSC.NASTRAN, SIMULIA/Abaqus

�� Multibody Dynamics (MBD) solvers: �� MSC.ADAMS (LMS/CADSI, RecurDyn distant seconds)

Key Associations Reacting to Mechatronics Convergence

�� : the only global vendor-neutral, not-for-profit association for Mechanical Engineering Simulation (MCAE) �� Grew out of FEA use in the UK Nuclear Industry in the early

�� .
