Calculix (CCX) 2.17 is out

prop_designprop_design
there looks to be some interesting new developments, in version 2.17:

PaStiX solver; http://pastix.gforge.inria.fr/files/README-txt.html
tetgen mesher; http://wias-berlin.de/software/index.jsp?id=TetGen&lang=1
being able to automatically re-mesh based on solution results

Those are the three that stood out to me.

CCX website is here; http://www.dhondt.de/

    I use TetGen, it will create meshes from some brutally ugly surfaces, and also has some useful error checking. I believe this is the mesher used in LS-DYNA.

    Still waiting for Riks or any other arc-length implementation...:(

    in the notes it says he implemented mortar contact. that might be useful. not really sure. it looks like it helps with contact and dissimilar meshes.

    Have someone worked with CFD using CCX?

    hi sergio,

    i haven't used any ccx feature that isn't built into mecway. i just listed some of the interesting things, to me, from the release notes. i have tried various cfd programs that are out there and wasn't impressed with any of them. i doubt i would be thrilled with anything ccx offers wrt cfd. but you never know. maybe one day someone will create a useful and easy to use cfd program that is accurate and runs on a laptop. but i'm not holding my breath.
