Hi
I can define an orthotropic material in Linear Elastic or I can define a Neo-Hookean etc. material in Hyperelastic, but how to define an orthotropic Neo-Hookean material?
Thanks!

Hi Chris,
There is no such thing as an anisotropic Neo-Hookean material! Using different Neo-Hookean material constants in different directions does not result in a hyperelastic formulation. There are however other anisotropic hyperelastic models. Check out the “Arterial Wall Mechanics” COMSOL model from the Gallery (Model #14499) for a very good example.
