init operator

This method initializes the operator. Once initialized the 'apply'-method can be called.

Returns: bool success flag

Implements ug::IOperator< GridFunction< TDomain, TAlgebra > >.

◆ init() [2/2]

template<class TDomain , class TAlgebra >

virtual void ug::ITimeIntegrator< TDomain, TAlgebra >::init ( grid_function_type const & u )

inlinevirtual

init operator depending on a function u

This method initializes the operator. Once initialized the 'apply'-method can be called. The function u is passed here, since the linear operator may be the linearization of some non-linear operator. Thus, the operator depends on the linearization point. If the operator is not a linearization, this method can be implemented by simply calling init() and forgetting about the linearization point.

Parameters

[in] u function (linearization point)

Returns: bool success flag

Reimplemented in ug::TimeIntegratorLinearAdaptive< TDomain, TAlgebra >.
