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.
