1 Short overview An all-purpose FEM simulation software for structural analysis : Plugged in a user-friendly environment : Salome_Meca 3 novembre 2007

Short overview of Code_Aster 1 A large scope of capabilities • Thermal and mechanical • Statics and dynamics, linear or not • Modal analysis, harmonic and random response • ≈ 400 finite elements : 3D, 2D, shells, beams, pipes … • Wide range of loadings • Interaction with other physics (coupled or not) : fluid, soil structure computation, electro-magnetism … 4 novembre 2007

Short overview of Code_Aster 1 Non linearities and specific models • Contact, friction • Large displacements, large deformations • Behaviour models ( ≈ 100 constitutive laws) • Porous media, fracture mechanics, damage, fatigue, welding, seismic analysis … 5 novembre 2007

2 Why we make it Specific requirements of nuclear industry • Regulatory design, safety Specific problems : ageing of structures, re-evaluation of margins • Stakes differ from manufacturing industry and software vendors. Research and developments • Capitalization of know-how and models, quick transfer to engineering • Mastering of source code, models … Choice of in-house development 8 novembre 2007

2 How we make it (some figures) 60 releases each year 200 in-house users 1.256 documents freely available ( 13.800 pages) 15 PHD for the 8 last years 250 new features in the code in 2007 2.000 tests runned for each release 200.000 CPU hours 4 training sessions, 40 listeners each ASTER as a free software : 30.000 downloads, 10. 000 hits a week 9 novembre 2007

2 How we make it 2000 source lines x 1.000 1800 nb tests 1600 Version 8 nb doc pages x 10 déc. 2006 1400 nb in-house users 1200 CPU hours x100 Version 7 déc. 2004 1000 mise en libre Version 6 800 nov. 2002 Version 5 600 oct. 2000 Version 2 oct. 93 Version 4 400 avr. 98 Version 3 juin 96 200 0 07/89 07/90 07/91 07/92 07/93 07/94 07/95 07/96 07/97 07/98 07/99 07/00 07/01 07/02 07/03 07/04 07/05 07/06 10 novembre 2007

2 How we make it A network of programmers (like a free software) • A core team in charge of : kernel development, integration, distribution … [~20 engineers.year] • Applicative projects : bring new models / developements [~40 engineers.year] • Continuous process : no V cycle, no predefined specifications • A life cycle of 2 years : the developped version is transfered to engineering after a qualification process 11 novembre 2007
