Detailed Description

template<class JacobianOperator>
class Dune::ACFem::DifferentiableEmptyBlockConstraints< JacobianOperator >

A class modelling differentiable do-nothing constraints.

Useful to define default-types in template arguments.

template<class DiscreteFunction , class Traits >

void Dune::ACFem::BlockConstraintsOperatorInterface< DiscreteFunction, Traits >::constrain ( DiscreteFunctionType &  w ) const

inlineinherited

The solution operator; unconditionally install the given constraints into the argument.

This "solves"

\[ w - g = 0 \]

for w.
