Detailed Description

template<class CQVectAutoDiff>
class mfem::pLaplaceAD< CQVectAutoDiff >

Implements integrator for a p-Laplacian problem. The integrator is based on a class QFunction utilized for evaluating the energy, the first derivative (residual) and the Hessian of the energy (the Jacobian of the residual). The template parameter CQVectAutoDiff represents the automatically differentiated energy or residual implemented by the user. CQVectAutoDiff::VectorFunc(Vector parameters, Vector state,Vector residual) evaluates the residual at an integration point. CQVectAutoDiff::Jacobian(Vector parameters, Vector state, Matrix hessian) evaluates the Hessian of the energy(the Jacobian of the residual).
