1970s David Hibbitt received his PhD from Brown University in Rhode Island
David became the first employee at MARC in 1971
Hibbitt & Karlsson Inc was formed in February 1978
Version 1 was written to meet a single goal –
Analysing the mechanical restraint of the core of a prototype fast breeder reactor, consisting of contacting, hexagonal-section fuel rods subject to thermal expansion and irradiation-induced swelling
15,000 lines of FORTRAN with four element types: beam, gap, truss, and SPHEX, which included elasticity with creep and swelling
Paul Sorensen joined in 1979
Hibbitt, Karlsson & Sorensen, Inc
Version 2 released to do pipe whip problems
Not yet called ‗Abaqus‘

1980s David Hibbitt described the Abaqus
products in an introductory class in
1982
A consistent philosophy for the last 30
years
If you bought a license of Abaqus in the
early 1980s HKS staff would come to
your site to load, compile & link it from
tape. Analysis input files would be
defined on cards...

1980s The company grew from 2 employees in1978...
...to 10 in 1983...
...to 25 in 1988
In 1985 HKS purchased its first computer: a DEC VAX 785
Manuals were written on IBM typewriters with exchangable heads to do Greek letters
All pictures were hand drawn by a RISD student
1987 release of the first version of Abaqus/Post
1978—46 m2 1982—230 m2 1980—110 m2 1985—460 to 740 m2

Clint‘s paper ―Due to the size of the FE model (7,654 elements)… a powerful computer was necessary to cope with the analysis – the CRAY 2 computer at the Harwell Research Laboratories‖
7,654 elements was very impressive…
Quotes from other papers
… the model consisted of 569 elements…
… the mesh consists of 303 CAX4R elements…
… a mesh consisting of 210 elements is used…

Analysis in the 1990s Full richness of model—less
engineering judgement required
(non-intuitive results)
Dedicated analysts
3-D models, typically only a few
components
Advanced physics and materials:
• Surface-based contact including
friction, hyperelasticity, plasticity,
etc.
Preprocessors are common

The User Meeting... From User Group Conferences to Regional User Meetings
A forum for a group of individuals
to share experience and knowledge
to learn about new capabilities
to interact with developers, support staff and management
to provide feedback and recommendations about products and services

Analysis in the 2010s Simulation ‗comes of age‘ in many industries
Primary driver for new designs
Central rather than peripheral role
Technology reaches significant levels of maturity, performance and robustness
Designs become simulation-driven
New generation of products designed through CAE
• Superior characteristics in performance, durability and price
Focus on Product in-situ
Higher levels of realism, fewer assumptions, less approximation
Increase in process integration, process automation, optimisation (design, topology)

Challenges The ability to handle large models is interesting, useful, but not necessarily a
good indicator of analysis effectiveness
What is more important today is the effectiveness of the complete simulation
lifecycle
Geometry, Meshing, Assembly, Execution, Visualisation
Interpretation, Exploration, Automation, Decision-making
The bottlenecks in that lifecycle have shifted in recent years
Different focus in the future, compared to today and to the past
No more predictions on model size...

The Future Analysis
Remove or reduce the bottlenecks from the complete lifecycle
Connect simulation even more into the wider market (consumers, manufacturers,
retailers)
Improve collaboration, automation, exploration
User meetings
To continue, to evolve...
Always Real rather than Virtual
