Detailed Description

Hyperelastic integrator for any given HyperelasticModel.

Represents \( \int W(Jpt) dx \) over a target zone, where W is the model's strain energy density function, and Jpt is the Jacobian of the target->physical coordinates transformation. The target configuration is given by the current mesh at the time of the evaluation of the integrator.
