Detailed Description

This class represents a nonlinear variational problem:

Find u in V such that

F(u; v) = 0  for all v in V^,

where V is the trial space and V^ is the test space.

Constructor & Destructor Documentation

NonlinearVariationalProblem()

NonlinearVariationalProblem::NonlinearVariationalProblem	(	std::shared_ptr< const Form >	F,
		std::shared_ptr< Function >	u,
		std::vector< std::shared_ptr< const DirichletBC > >	bcs,
		std::shared_ptr< const Form >	J = nullptr )

Create nonlinear variational problem, shared pointer version. The Jacobian form is specified which allows the use of a nonlinear solver that relies on the Jacobian (using Newton's method).
