Detailed Description

template<int dim>
class aspect::Particle::Property::Interface< dim >

Interface provides an example of how to extend the Particle class to include related particle data. This allows users to attach scalars/vectors/tensors/etc to particles and ensure they are transmitted correctly over MPI and written to output files.

Constructor & Destructor Documentation

§ ~Interface()

template<int dim>
virtual aspect::Particle::Property::Interface< dim >::~Interface ( )
virtualdefault

Destructor. Made virtual so that derived classes can be created and destroyed through pointers to the base class.

§ initialize()

template<int dim>
virtual void aspect::Particle::Property::Interface< dim >::initialize ( )
virtual

§ initialize_one_particle_property()

template<int dim>
virtual void aspect::Particle::Property::Interface< dim >::initialize_one_particle_property ( const Point< dim > &  position,
std::vector< double > &  particle_properties 
) const

§ update_particle_property()

template<int dim>
virtual void aspect::Particle::Property::Interface< dim >::update_particle_property ( const unsigned int  data_position,
const Vector< double > &  solution,
const std::vector< Tensor< 1, dim >> &  gradients,
typename ParticleHandler< dim >::particle_iterator &  particle 
) const
virtual

Update function. This function is called every time an update is request by need_update() for every particle for every property. It is obvious that this function is called a lot, so its code should be efficient. The interface provides a default implementation that does nothing, therefore derived plugins that do not require an update do not need to implement this function.

Parameters
[in]data_positionAn unsigned integer that denotes which component of the particle property vector is associated with the current property. For properties that own several components it denotes the first component of this property, all other components fill consecutive entries in the particle_properties vector.
[in]solutionThe values of the solution variables at the current particle position.
[in]gradientsThe gradients of the solution variables at the current particle position.
[in,out]particleThe particle that is updated within the call of this function. The particle location can be accessed using particle->get_location() and its properties using particle->get_properties().

It is obvious that this function is called a lot, so its code should be efficient.

Parameters
[in]data_positionAn unsigned integer that denotes which component of the particle property vector is associated with the current property.

[in]positionThe current particle position.
[in]solutionThe values of the solution variables at the current particle position.
[in]gradientsThe gradients of the solution variables at the current particle position.
[in,out]particle_propertiesThe properties of the particle that is updated within the call of this function.
Deprecated:
Use update_particle_property() instead.

Reimplemented in aspect::Particle::Property::CrystalPreferredOrientation< dim >, aspect::Particle::Property::CpoElasticTensor< dim >, and aspect::Particle::Property::CpoBinghamAverage< dim >.

§ need_update()

template<int dim>
virtual UpdateTimeFlags aspect::Particle::Property::Interface< dim >::need_update ( ) const
virtual

Returns an enum, which determines at what times particle properties are updated. The default implementation returns update_never, which signals that particle properties should never be updated. See the documentation of UpdateTimeFlags for a list of possible values and examples for their use. Every plugin that implements this function should return the value appropriate for its purpose, unless it does not need any update, which is the default. This option saves considerable computation time in cases, when no plugin needs to update particle properties over time.

§ get_needed_update_flags()

template<int dim>
virtual UpdateFlags aspect::Particle::Property::Interface< dim >::get_needed_update_flags ( ) const
virtual

§ late_initialization_mode()

template<int dim>
virtual InitializationModeForLateParticles aspect::Particle::Property::Interface< dim >::late_initialization_mode ( ) const
virtual

Returns an enum, which determines how this particle property is initialized for particles that are created later than the initial particle generation, e.g. to balance the particle load or prevent empty cells. The default implementation returns interpolate, which will use the particle interpolator to set the new particle properties to a value that is interpolated from the other particles in the cell. See the documentation of InitializationModeForLateParticles for a list of possible values and examples for their use. Every plugin that implements this function should return the value appropriate for its purpose, unless it wants to use the default value.

Reimplemented in aspect::Particle::Property::CrystalPreferredOrientation< dim >, aspect::Particle::Property::GrainSize< dim >, and aspect::Particle::Property::InitialComposition< dim >.

§ get_property_information()

template<int dim>
virtual std::vector<std::pair<std::string, unsigned int> > aspect::Particle::Property::Interface< dim >::get_property_information ( ) const
pure virtual

§ declare_parameters()

template<int dim>
static void aspect::Particle::Property::Interface< dim >::declare_parameters ( ParameterHandler &  prm)
static

Declare the parameters this class takes through input files. Derived classes should overload this function if they actually do take parameters; this class declares a fall-back function that does nothing, so that property classes that do not take any parameters do not have to do anything at all.

This function is static (and needs to be static in derived classes) so that it can be called without creating actual objects (because declaring parameters happens before we read the input file and thus at a time when we don't even know yet which property objects we need).

§ parse_parameters()

template<int dim>
virtual void aspect::Particle::Property::Interface< dim >::parse_parameters ( ParameterHandler &  prm)
virtual

Read the parameters this class declares from the parameter file. The default implementation in this class does nothing, so that derived classes that do not need any parameters do not need to implement it.
