Detailed Description
template<class JacobianOperator, class LInvOp>
class Dune::Fem::NewtonInverseOperator< JacobianOperator, LInvOp >
class Dune::Fem::NewtonInverseOperator< JacobianOperator, LInvOp >
inverse operator based on a newton scheme
- Template Parameters
-
Op operator to invert (must be a DifferentiableOperator) LInvOp linear inverse operator
- Note
- Verbosity of the NewtonInverseOperator is controlled via the paramter fem.solver.nonlinear.verbose; it defaults to fem.solver.verbose.
- Similar to CG solver the initial guess should take the constraints into account. In this case we need the initial residual to be zero on the boundary, i.e., when calling operator()(u,w) then w=g+u should hold on the Dirichlet boundary. This way we do not explicitly need to call the constraints here.
