    These are the one with which I am most familiar. There are others, but these are the biggies. We use ABAQUS as well as our own proprietary methods, particularly for dynamic, large strain and nonlinear FEA.


    ABAQUS (HKS) - for nonlinear Finite Element Analysis (FEA)

    I remember someone here telling me about Warp 3D, which is supposed to be pretty good although I've never used it, can anyone remember who told me about it?! :smile:

    Edit: Ahh, that would be Perennial then!

    A couple more, but I am not familiar with these:

    http://www.intes.de/ - PERMAS Finite Element Software System.
    http://www.intes.de/english/projects
    http://www.nafems.de/ (auf Deutsch)

    http://www.comsol.com/ - Multiphysics (?)
    http://www.comsol.com/products/

    And another package we use, but I don't know much about it.

    ADINA (Automatic Dynamic Incremental Nonlinear Analysis) - ADINA R & D, Inc.
    http://www.adina.com/
    http://www.adina.com/products.shtml

    The non-linear part is key. Not too many packages necessarily do it right!

    .... I'll continue my add then :biggrin: (without "too much" of an affiliation btw): completely free, has properties equal and in many areas beyond the "commercial monsters" and complete access to source (along with the usuals like extremely resource efficient & robust & continuously under development).

    .... if you want to go dynamic, Adina has a rep of being a stable and accurate in complex nonlinear problems (involving usually contact, that being nonlinear as well).

    Comsol was previously known as Femlab, which is yes essentially a multiphysics code. Meaning, that it suits very well to problems involving different types of couplings between various PDEs (can be several, unidirectional or totally coupled etc., have used it e.g. in solving coupled mass diffusion-thermal-mechanical-damage-fluid problems, great code for such problems). One of its strengths for a researcher in particular is access to the PDE implementations, can easily implement own modifications (or totally new eqs and solve using the FE kernel), introduce own material models etc. + It's adaptive in many directions (like hp-FEA and some other aspects as well).

    Morbius posted an article from Physics Today in Nuclear Engineering which had an add for PDESolutions. Anybody use this? It seems to be a Multiphysics package. The example shows dynamic meshing - pretty cool.

    .... I've considered it kind of like the little-bro of Comsol/Femlab. A scripting multiphysics FEA package with a h-adaptive mesh generator, nice package for numerically solving own PDEs (=customizing for whatever equation and equations with any degree of coupling) and comes with a price tag a tad more decent than its bigger-bro(s).

    Random vibration and FEM

    I am wondering if deterministic method such as FEM is reliable for computation of random response to dynamic system.

    We are developing a method to predict the response of a flat shell element to a pressure filed arising from the fully developed turbulent boundary layer of a subsonic flow. Fluctuating wall pressures induced by fully developed turbulent boundary layer are random, so we must rely on the statistical properties of the turbulent flow, such cross spectral density and cross correlation functions.
