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.

overrideprotectedvirtual

Subclasses should override to choose a default integration rule.

This method is intended to be overridden by subclasses to choose an appropriate integration rule based on the finite element spaces and/or element transformation. The trial_fe and test_fe should be equal for linear forms. The default base-class implementation returns null, which assumes that an appropriate rule is provided by another means, or that null integration rules are handled appropriately by the caller.

Reimplemented from mfem::Integrator.

◆ GetElementEnergy()

real_t mfem::HyperelasticNLFIntegrator::GetElementEnergy	(	const FiniteElement &	el,

Computes the integral of W(Jacobian(Trt)) over a target zone.

Parameters

[in]	el	Type of FiniteElement.
[in]	Ttr	Represents ref->target coordinates transformation.
[in]	elfun	Physical coordinates of the zone.
