The CAE - Finite Elements competitive market . FE market: linear and non linear: . MSC suite: Nastran and MARC . Ansys . Abaqus . Nei Nastran – NX Nastran . LS Dyna . Cosmos . ALGOR . Radioss . Pamcrash 1 - ASD Competence Center - 2011 Linear Market . 2 categories: . High end software: SAMCEF, ANSYS, Nastran (all of them) . No big difference between them (NL contact in SAMCEF maybe?) . Branding, GUI and existing models are the differentiators . Low end: Cosmos, ALGOR, Catia GPS . Sold as add-on to CAD packages . Limited features available . Mesh “across the CAD” and push a few buttons to get results . Used mostly when rough results are OK . Cost ~5k€ 2 - ASD Competence Center - 2011 Non Linear market . Implicit: MSC Marc, Abaqus, ANSYS, SAMCEF Mecano, Recurdyn & Dafool . Abaqus and MSC Marc are more dedicated to pure structural analysis (include very large defos, metal forming for example) . SAMCEF Mecano is better suited for Flexible Dynamics Analyses . SAMCEF Mecano best suited for slow dynamics (10-> 500 Hz, > 10s simulation time) . Explicit: LS Dyna, Abaqus, Radioss . Suited for fast dynamic analyses (impact, crash, blasts,…) . Limited simulation time due to very small time steps (1e-6s) . Still popular to model slow dynamics with Explicit, even of not a good idea 3 - ASD Competence Center - 2011 MSC offer . Is the sum of purchases, very little internal developments . Nastran is made of many modules: SOL XXX . Comes with the Masterkey license concept: tokens can be used to launch any solver . Used to be very heterogeneous. Nastran, Marc and Adams came with no compatibility and different GUI. Better now with MD Patran/Nastran? Adams still out. Nastran = the standard for linear analysis in aeronautics. Impossible to change that! . MSC was bought by equity firm Symphony in 2009 and relaunched a lot of products developments since then (MD Patran, Adams 2010…) 4 - ASD Competence Center - 2011 ANSYS offer . The most homogeneous and complete competitor . Strong hold on energy market, less present in aero . Most products developed in-house . Focus on multiphysics, especially FSI. Own a couple of CFD codes (Fluent, CFX) . Mechanical offer contains few modules: only ANSYS Structural and ANSYS Mechanical . Have a FMBD solution but don’t advertise it (yet) too much . ANSYS Workbench = important player on the GUI market, even for non ANSYS users 5 - ASD Competence Center - 2011 Abaqus offer . Abaqus purchased by Dassault in 2005. Became the core of Simulia, the simulation platform of Dassault . Standard solution for structural non linear analyses . Offer both Implicit and Explicit . No linear package => always comes on top of something else 6 - ASD Competence Center - 2011 Recurdyn and Dafool . For Flexible MBS, come with similar messages as SAMCEF Mecano: real FEA inside MBS . Are somewhat popular in Asia, not anywhere else . Harmed us a lot in Korea 5 years ago, but the bubble exploded 7 - ASD Competence Center - 2011 GUI market . SAMCEF Field . Patran : MSC GUIs; old fashioned but still very much used (old standard) . ANSYS Workbench: multiphysics oriented; includes workflows and model management on top of FEA GUI . Hypermesh: Most popular FEA GUI for mesh generation, driving +/- 50% of Nastran licenses. 8 - ASD Competence Center - 2011.
