Re: [Getfem-users] Getfem version and non linear elasticity models

[Yves Renard]

Dear Sébastien,

The documentation is indeed for the svn version (future version 4.3)
which should be released soon.
The documentation evolves with the project.

Neo-Hookean material is only available on the svn version yes. And it is
far more easy to add a new hyperelastic potential with the generic
assembly now. So I recommand you to install the current svn version.
Here is a link to a pre 4.3 release:
