No, you do not set the Hertz model at all (the corresponding law functor
would be:

You set a linear model and at the same time you introduce some attributes in
python, like ContactModel.betan, which have no effect. As Bruno said, you
need a new Ip functor if you want to use the existing capillary model with
the Hertzian law. Chiara
