Cool. Thanks. That sounds good.

The code is finally in the repository, try it please. If someone could verify it against some other code with a hyperelastic neo-Hookean material model on a simple example, I would be very glad as I do not have time to do it myself now.

It's an initial attempt to solve such nonlinear problems in sfepy, so expect bugs and deficiencies.

See input/hyperelastic.py for example usage.

Run ./runTests.py --debug tests/test_input_hyperelastic.py

and look at the animation in output-tests/test_hyperelastic.**.vtk

update: just added Mooney-Rivlin material model.
