Detailed Description

Container to store all ParticleSpecies.

The SpeciesHandler is a container to store all ParticleSpecies. It is implemented by a vector of pointers to ParticleSpecies.

Definition at line 38 of file SpeciesHandler.h.

Constructor & Destructor Documentation

SpeciesHandler::SpeciesHandler

(

)

Default constructor, it creates an empty SpeciesHandler.

Constructor of the SpeciesHandler class. It creates an empty SpeciesHandler.

Definition at line 73 of file SpeciesHandler.cc.

References DEBUG, and logger.

{
    logger(DEBUG, "SpeciesHandler::SpeciesHandler() finished");
}

SpeciesHandler::SpeciesHandler

(

const SpeciesHandler &

other

)

Constructor that copies all species and the pointer to the DPMBase from the given SpeciesHandler.

Parameters

[in]

other

The SpeciesHandler that has to be copied.

This is not a copy constructor! This constructor copies only all BaseSpecies and MixedSpecies and copies the pointer to the DPMBase. It sets all other data members to 0 or nullptr.

Definition at line 84 of file SpeciesHandler.cc.

    for (BaseSpecies* mixSpec : other.mixedObjects_) 
    {

}

SpeciesHandler::~SpeciesHandler

(

)

Destructor, it destructs the SpeciesHandler and all ParticleSpecies it contains.

Destructor: first destroys the objects of the BaseHandler, then destroys the mixedObjects

Definition at line 128 of file SpeciesHandler.cc.

}

Member Function Documentation

void SpeciesHandler::addObject ( ParticleSpecies *const  S )

virtual

Adds a new ParticleSpecies to the SpeciesHandler.

Parameters

[in]

S

A pointer to the ParticleSpecies that has to be added.

First, add the ParticleSpecies to the vector of ParticleSpecies (object_), then construct all MixedSpecies. Tell the ParticleSpecies that this is its handler and compute all masses and whether it should use angular degrees of freedom.

Note: The MixedSpecies objects are initialized with averaged values from both species: e.g., the mixedSpecies between Species A and B will have a stiffness $fk=(1/k_a+1/k_b)^{-1}$f, you have to change the MixedSpecies properties if you don't like these defaults.

Todo:

TW don't put logger messages that only make sense for one application!

unsigned int SpeciesHandler::getMixedId	(	const unsigned int	id1,
		const unsigned int	id2
	)		const

Gets the Id of the behaviour between two given species.

Parameters

[in]	id1	Id of the first species.
[in]	id2	Id of the second species.

Returns

An unsigned integer that denotes the Id of the mixed species.

The numbering of the mixed species is 0-1, 0-2, 1-2, 0-3, 1-3, 2-3, 0-4, 1-4, 2-4, 3-4, ..., where each pair of numbers a and b denotes the mixed species between ParticleSpecies a and b. Thus, first compute which id has a higher value, the id of the mixed species is then given by (maxId*(maxId-1))/2 + minId.

BaseSpecies * SpeciesHandler::getMixedObject	(	const unsigned int	id1,
		const unsigned int	id2
	)

Gets the mixed object that is constructed from two given species.

Parameters

[in]	id1	Id of the first BaseSpecies.
[in]	id2	Id of the second BaseSpecies.

Returns

A pointer to an object that is a MixedSpecies of both input Species.

Todo:

This function should probably be made private. The user should use the function SpeciesHandler::getMixedObject(const U* S, const U* T), which deals with pointers.

SpeciesHandler SpeciesHandler::operator=

(

const SpeciesHandler &

rhs

)

Assignment operator that copies all species and the pointer to the DPMBase from the given SpeciesHandler.

Parameters

[in]

rhs

The BoundaryHandler on the right hand side of the assignment.

Returns

The SpeciesHandler that is a copy of the input SpeciesHandler rhs.

This is not a copy assignment operator! It copies only all BaseSpecies and MixedSpecies and copies the pointer to the DPMBase. It sets all other data members to 0 or nullptr.

void SpeciesHandler::readObject ( std::istream &  is )

virtual

Reads Species data into the SpeciesHandler from restart file.

Parameters

[in]

is

The input stream from which the information is read.

First determine the type of the object we want to read, then read the actual object. After that, clear the mixed objects and read the mixed objects.

Todo:

IFCD how does the numbering of mixedSpecies_ work? the numbering of mixed species is 01, 02, 12, 03, 13, 23, 04, 14, 24, 34, i.e. if you add the n-th ParticleSpecies, then you have to add n-1 MixedSpecies. So here I remove the last n-1 MixedSpecies and add n-1 new ones.

ParticleSpecies * SpeciesHandler::readOldObject

(

std::istream &

is

)

Reads ParticleSpecies into the SpeciesHandler from old-style restart data.

Parameters

[in]

is

The input stream from which the information is read.

Returns

A pointer to the ParticleSpecies that has just been read.

To read the old object, we first make a stringstream of the line that describes this ParticleSpecies. After that, we read the properties one by one, first the stiffness and after that the other properties. We stop when we either reach the end of the file(eof) or if a string is not recognized as a property.

void SpeciesHandler::removeObject ( unsigned const int  index )

virtual

Remove the ParticleSpecies with given id.

Parameters

[in]

index

The index of which ParticleSpecies has to be removed from this ParticleHandler.

The ParticleSpecies with index is removed and the last ParticleSpecies in the vector is moved to its position. It also removes all mixed species for this ParticleSpecies.

Reimplemented from BaseHandler< ParticleSpecies >.

bool SpeciesHandler::useAngularDOFs

void SpeciesHandler::write ( std::ostream &  os ) const

Parameters

First write "Species" and the amount of species in this handler, then write all ParticleSpecies and MixedSpecies.

    there is a reason. Curernt architecture does not allow this
    \todo define new restart format. @dducks
    
    The code is written such that it writes PS0, then PS1 and MS01, then PS2 and 
    MS02, MS12, and so on (PS=ParticleSpecies, MS=MixedSpecies). We can change 
    the restart format, but we should write the read(os) function such that
