Detailed Description

template<typename T, typename FEM>
class Dune::PDELab::DGMaxwellTemporalOperator< T, FEM >

a local operator for the mass operator of a vector valued lfs (L_2 integral)

\begin{align*} \int_\Omega uv dx \end{align*}

This is pretty much the same as PowerL2. Differences are: this operator evaluates the child basis only once for child 0 an reuses that for the other components this operator caches basis evaluations

void Dune::PDELab::InstationaryLocalOperatorDefaultMethods< T::Traits::RangeFieldType >::postStage ( )
inlineinherited

to be called once at the end of each stage

void Dune::PDELab::InstationaryLocalOperatorDefaultMethods< T::Traits::RangeFieldType >::postStep ( )
inlineinherited

to be called once at the end of each time step

Note
With the OneStepMethod and the ExplicitOneStepMetod, for reasons unknown this is only called for temporal but not for spatial local operators. With the MultiStepMethod this is called for all local operators.
void Dune::PDELab::InstationaryLocalOperatorDefaultMethods< T::Traits::RangeFieldType >::preStage ( RealType  time,
int  r 
)
inlineinherited

to be called once before each stage

Parameters
timeTime of the stage
rNumber of the stage, r ∈ [1, nstages] inclusive, where nstages is the number of stage in the step given in the previous call to preStep()
Note
For ExplicitOneStepMethod the time given here for stage 1 may be incorrect, since the time step size is only finally determined after the first stage has been assembled.
For the MultiStepMethod, this is called once after preStep() with r=1.
void Dune::PDELab::InstationaryLocalOperatorDefaultMethods< T::Traits::RangeFieldType >::preStep ( RealType  time,
RealType  dt,
int  stages 
)
inlineinherited

to be called once before each time step

Parameters
timeTime at beginning of the step.
dtSize of time step.
stagesNumber of stages to do in the step. For the MultiStepMethod this is always 1.
Note
For ExplicitOneStepMethod the dt given here may be incorrect, since the time step size is only finally determined after the first stage has been assembled.
For the MultiStepMethod the number of stages is given as
  1. Since there are no times of evaluation in the middle of the step, a multi-step method is similar to a one step method with one stage.
void Dune::PDELab::InstationaryLocalOperatorDefaultMethods< T::Traits::RangeFieldType >::setTime ( T::Traits::RangeFieldType  t_)
inlineinherited

set time for subsequent evaluation

This method set the time for subsequent calls to the alpha_*(), lambda_*(), jacobian_*() and jacobian_apply_*() methods.

Note
For ExplicitOneStepMethod the time given here in the first stage may be incorrect, since the time step size is only finally determined after the first stage has been assembled.
RealType Dune::PDELab::InstationaryLocalOperatorDefaultMethods< T::Traits::RangeFieldType >::suggestTimestep ( RealType  dt) const
inlineinherited

to be called after stage 1

Note
Only used by the ExplicitOneStepMethod.

This may be called on the spatial local operator in the case of an explicit one step scheme. It is called after stage 1 has been assembled (so the time given to preStep() may not apply anymore in this case). All the alpha_*() and lambda_*() methods should have been called, so they are a good place to generate the information returned here.
