Detailed Description

template<int dim>
class aspect::Postprocess::Particles< dim >

A Postprocessor that creates particles, which follow the velocity field of the simulation. The particles can be generated and propagated in various ways and they can carry a number of constant or time-varying properties. The postprocessor can write output positions and properties of all particles at chosen intervals, although this is not mandatory. It also allows other parts of the code to query the particles for information.

Member Function Documentation

§ execute()

template<int dim>

std::pair<std::string,std::string> aspect::Postprocess::Particles< dim >::execute ( TableHandler & statistics )

overridevirtual

Execute this postprocessor. Derived classes will implement this function to do whatever they want to do to evaluate the solution at the current time step.

Parameters

[in,out] statistics An object that contains statistics that are collected throughout the simulation and that will be written to an output file at the end of each time step. Postprocessors may deposit data in these tables for later visualization or further processing.

Returns: A pair of strings that will be printed to the screen after running the postprocessor in two columns; typically the first column contains a description of what the data is and the second contains a numerical value of this data. If there is nothing to print, simply return two empty strings.

Implements aspect::Postprocess::Interface< dim >.

§ save()

template<int dim>

void aspect::Postprocess::Particles< dim >::save ( std::map< std::string, std::string > & status_strings ) const

overridevirtual

Save the state of this object.

Reimplemented from aspect::Postprocess::Interface< dim >.

§ load()

template<int dim>

void aspect::Postprocess::Particles< dim >::load ( const std::map< std::string, std::string > & status_strings )

overridevirtual

Restore the state of the object.

Reimplemented from aspect::Postprocess::Interface< dim >.

§ serialize()

template<int dim>

template<class Archive >

void aspect::Postprocess::Particles< dim >::serialize	(	Archive &	ar,
		const unsigned int	version
	)

Serialize the contents of this class as far as they are not read from input parameter files.

§ declare_parameters()

template<int dim>

static void aspect::Postprocess::Particles< dim >::declare_parameters ( ParameterHandler & prm )

static

Declare the parameters this class takes through input files.

§ parse_parameters()

template<int dim>

void aspect::Postprocess::Particles< dim >::parse_parameters ( ParameterHandler & prm )

overridevirtual

Read the parameters this class declares from the parameter file.

Reimplemented from aspect::Postprocess::Interface< dim >.

§ set_last_output_time()

template<int dim>

void aspect::Postprocess::Particles< dim >::set_last_output_time ( const double current_time )

private

Set the time output was supposed to be written. In the simplest case, this is the previous last output time plus the interval, but in general we'd like to ensure that it is the largest supposed output time, which is smaller than the current time, to avoid falling behind with last_output_time and having to catch up once the time step becomes larger. This is done after every output.

§ writer()

template<int dim>

static void aspect::Postprocess::Particles< dim >::writer	(	const std::string	filename,
		const std::string	temporary_filename,
		const std::string *	file_contents
	)

staticprivate

A function that writes the text in the second argument to a file with the name given in the first argument. The function is run on a separate thread to allow computations to continue even though writing data is still continuing. The function takes over ownership of these arguments and deletes them at the end of its work.

§ write_master_files()

template<int dim>

void aspect::Postprocess::Particles< dim >::write_master_files	(	const internal::ParticleOutput< dim > &	data_out,
		const std::string &	solution_file_prefix,
		const std::vector< std::string > &	filenames
	)

private

Write the various master record files. The master files are used by visualization programs to identify which of the output files in a directory, possibly one file written by each processor, belong to a single time step and/or form the different time steps of a simulation. For Paraview, this is a .pvtu file per time step and a .pvd for all time steps. For VisIt it is a .visit file per time step and one for all time steps.

Parameters

data_out	The DataOut object that was used to write the solutions.
solution_file_prefix	The stem of the filename to be written.
filenames	List of filenames for the current output from all processors.

Member Data Documentation

§ output_interval

template<int dim>

double aspect::Postprocess::Particles< dim >::output_interval

private

Interval between output (in years if appropriate simulation parameter is set, otherwise seconds)

Definition at line 187 of file particles.h.

§ last_output_time

template<int dim>

double aspect::Postprocess::Particles< dim >::last_output_time

private

Records time for next output to occur

Definition at line 192 of file particles.h.

§ output_file_number

template<int dim>

unsigned int aspect::Postprocess::Particles< dim >::output_file_number

private

Consecutively counted number indicating the how-manyth time we will create output the next time we get to it.

Definition at line 208 of file particles.h.

§ output_formats

template<int dim>

std::vector<std::string> aspect::Postprocess::Particles< dim >::output_formats

private

Graphical output format.

Definition at line 213 of file particles.h.

§ times_and_pvtu_file_names

template<int dim>

std::vector<std::pair<double,std::string> > aspect::Postprocess::Particles< dim >::times_and_pvtu_file_names

private

A list of pairs (time, pvtu_filename) that have so far been written and that we will pass to DataOutInterface::write_pvd_record to create a master file that can make the association between simulation time and corresponding file name (this is done because there is no way to store the simulation time inside the .pvtu or .vtu files).

Definition at line 223 of file particles.h.

§ times_and_vtu_file_names

template<int dim>

std::vector<std::pair<double,std::vector<std::string> > > aspect::Postprocess::Particles< dim >::times_and_vtu_file_names

private

A corresponding variable that we use for the .visit files created by DataOutInterface::write_visit_record. The second part of a pair contains all files that together form a time step.

Definition at line 230 of file particles.h.

§ output_file_names_by_timestep

template<int dim>

std::vector<std::vector<std::string> > aspect::Postprocess::Particles< dim >::output_file_names_by_timestep

private

A list of list of filenames, sorted by timestep, that correspond to what has been created as output. This is used to create a master .visit file for the entire simulation.

Definition at line 237 of file particles.h.

§ xdmf_entries

template<int dim>

std::vector<XDMFEntry> aspect::Postprocess::Particles< dim >::xdmf_entries

private

A set of data related to XDMF file sections describing the HDF5 heavy data files created. These contain things such as the dimensions and names of data written at all steps during the simulation.

Definition at line 245 of file particles.h.

§ group_files

template<int dim>

unsigned int aspect::Postprocess::Particles< dim >::group_files

private

VTU file output supports grouping files from several CPUs into one file using MPI I/O when writing on a parallel filesystem. 0 means no grouping (and no parallel I/O). 1 will generate one big file containing the whole solution.

Definition at line 253 of file particles.h.

§ temporary_output_location

template<int dim>

std::string aspect::Postprocess::Particles< dim >::temporary_output_location

private

On large clusters it can be advantageous to first write the output to a temporary file on a local file system and later move this file to a network file system. If this variable is set to a non-empty string it will be interpreted as a temporary storage location.

Definition at line 262 of file particles.h.

§ write_in_background_thread

template<int dim>

bool aspect::Postprocess::Particles< dim >::write_in_background_thread

private

File operations can potentially take a long time, blocking the progress of the rest of the model run. Setting this variable to 'true' moves this process into a background thread, while the rest of the model continues.

Definition at line 270 of file particles.h.

§ background_thread

template<int dim>

std::thread aspect::Postprocess::Particles< dim >::background_thread

private

Handle to a thread that is used to write data in the background. The writer() function runs on this background thread.

Definition at line 276 of file particles.h.

§ exclude_output_properties

template<int dim>

std::vector<std::string> aspect::Postprocess::Particles< dim >::exclude_output_properties

private

Stores the particle property fields which are excluded from output to the visualization file.

Definition at line 282 of file particles.h.
