The CAE - Finite Elements competitive market

. FE market: linear and non linear: . MSC suite: and MARC . . . 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 , 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.
