[in]	mol_name	valid molecule names (as defined in the LAMMPS input file. e.g., if you used this command: "molecule mmmTCP ./TCP.xyz", then mol_name should be "mmmTCP").

Note: This function is a wrapper around the compute_center of molecule.h.; THis function can be helpful if you want to get the molecule center before the start of the run (i.e., to populate kMC events etc).; This function HAS to be used to initialize the events list for deposition events. If not used you will get a segmentation fault as the molecule center will not be calculated.

◆ copyDoubleArray3D()

◆ deleteBond()

		const LAMMPS_NS::tagint &	atom2id,
		const bool	special
	)

Deletes an existing bond between atom1 and atom2.

Parameters

[in,out]	lmp	pointer to previously instantiated LAMMPS object.
[in]	atom1id	ID of the first atom.
[in]	atom2id	ID of the second atom.
[in]	special	if true, then the delete_bonds LAMMPS command is called with the "special" keyword.

Note: This function is a wrapper of this LAMMPS command: https://docs.lammps.org/delete_bonds.html; The delete_bonds command in LAMMPS deletes ALL bonds of a specific type between 2 atoms Hence, to delete one specific bond, we temporarily move the bond to a dummy bond type group and then invoke the delete_bonds command Such method is safe since ONLY ONE BOND CAN BE FORMED BETWEEN A SET OF ATOMS (e.g., one P atom and one O atom should only have one bond between each other. If you want 2 specific atom IDS to form more that one bond between (e.g., a double/triple bond), consider using one bond type instead of 3 separate bond types.; If an bond does not exist between the 2 atoms, LAMMPS will not throw an error! This happens because the bond deletion group will be empty by the time the delete_bonds command is called.; This function uses a dummy group named bonddel to delete atoms. Do not define another group with the same name in your LAMMPS input file.

◆ deleteDesorbedAtoms()

void PAPRECA::deleteDesorbedAtoms	(	LAMMPS_NS::LAMMPS *	lmp,

		int &	proc_id,
		const int &	nprocs,
		double &	film_height,
		ATOM2BONDS_MAP &	atomID2bonds
	)

This function is always called but performs computations only if the user has set a desorption height cutoff in the PAPRECA input file. The present function compares the z-coordinate of each atom with the desorption height cutoff. If any z-coordinate value is greater than or equal to the desorption height cutoff, the associated atom (along with its bonded atoms) is deleted. Currently, the user can select between two different algorithms: 1) gather_local (see fillDelidsLocalVec() function description/notes), and 2) gather_all (see fillDelidsVec() function description/notes). A comparison of the performance between the two algorithms is not currently available. However, as a quick note, it can be mentioned that gather_all is expected to be more memory intensive, since it calls the LAMMPS function lammps_gather_atoms_concat() to gather the coordinates of non-consecutive IDs on the master proc.

Parameters

[in,out]	lmp	pointer to LAMMPS object.
[in]	papreca_config	object of the PAPRECA::PaprecaConfig class that stores global variables and settings for the current PAPRECA run.
[in]	proc_id	ID of current MPI process.
[in]	nprocs	total number of MPI processes.
[in]	film_height	height at current PAPRECA step.
[in,out]	atomID2bonds	PAPRECA::ATOM2BONDS_MAP container (i.e., std::unordered_map< LAMMPS_NS::tagint parent_atomID , std::vector< PAPRECA::Bond > >). The atomID2bonds container provides direct access to all the bonds of the parent atom.

See also: PAPRECA::fillDelidsLocalVec(), PAPRECA::fillDelidsVec()

		const int &	is_displacive,
		const int &	diffused_type
	)

Executes a diffusion operation (i.e., moves if the diffusion is displacive, or creates an atom if the diffusion is non-displacive).

Parameters

[in,out]	lmp	pointer to previously instantiated LAMMPS object.
[in]	vac_pos	coordinates (x,y, and z) of vacancy.
[in]	parent_id	ID of parent candidate atom.
[in]	parent_type	atom type of parent candidate atom.

[in]	diffused_type	type of diffused atom. Can be the same as parent type or can be set to a different type if you wish to change the atom type after performing a diffusion event.

See also: createAtom(), deleteAtoms()

Note: If diffusion is displacive, the original atom moves. Instead of deleting bonds to move an atom it would be easier to delete the diffusing atom and spawn it again. This approximation introduces an error: it assumes that the charge of the atom becomes zero during diffusion. However, if you use any charge equilibration scheme this shouldn't be an issue because the atom is going to obtain the correct charge during equilibration. More sophisticated solutions would include: Actual moving of atom or even transferring (using set functions of charges).; If diffusion is non-displacive, we create a new atom in the vacancy position instead of moving the parent atom. Again, we assume that the charge of the atom is 0 to begin with.

See also: lammps_wrappers.h and lammps_wrappers.cpp

Note: Information should be communicated among the processes before the execution of an event. This happens because to execute an event we need to call lammps_command or lmp->input->one. lammps_command and lmp->input->one functions have to be called simultaneously by all MPI processes (otherwise the program will hang).; This function will almost certainly require a few changes if the user decides to modify the existing classes of events (bond form/break, deposition, diffusion) or add a new class of events. If changes are made the user will have to find a way to communicate data between procs (similar solutions as the solutions above can be used, of course).

◆ fillAndSortIndexedRatesVec()

void PAPRECA::fillAndSortIndexedRatesVec	(	double *	arr,
		const int &	arr_size,
		DOUBLE2INTPAIR_VEC &	rates_indexed
	)

Uses std::sort to sort a double array. Typically used to sort rates vector in ascending order. Sorting helps with faster event selection. It also ensures repeatability (if the same random number seed is used), because the event enumeration is maintained even if the domain decomposition numbering changes (i.e., if MPI decides to decompose the domain differently). The sorting is not performed on the array itself but on an auxiliary std::vector< std::pair< double , int > > containers that helps us sort while maintaining the index of events. This is necessary, since each time we stochastically select an event using the rates array, we have to link it (by index) to the correct PAPRECA::Event.

Parameters

[in]	arr	double array container.
[in]	arr_size	size of arr.
[in,out]	rates_indexed	std::vector< std::pair< double , int > > container used for ascending sorting.

◆ fillDelidsLocalVec()

		const double &	desorb_cut,
		std::vector< LAMMPS_NS::tagint > &	delids_local,
		ATOM2BONDS_MAP &	atomID2bonds
	)

Called by deleteDesorbedAtoms() and only when the delete_desorbed algorithm is set to gather_local. The function compares the z-coordinate of an atom. If the atom z-value is higher than desorb_cut, the atom ID is marked for deletion (i.e., inserted in the delids_local container) and it is later deleted along with its bonded atoms (retrieved from atomID2bonds map).

Parameters

[in]	lmp	pointer to LAMMPS object.
[in]	desorb_cut	cutoff distance for atom deletion. Atoms whose z-coordinate is equal to or greater than desorb_cut are marked for deletion.
[in,out]	delids_local	vector of collected atom IDs (delids_local will be different on each MPI process).
[in]	atomID2bonds	PAPRECA::ATOM2BONDS_MAP container (i.e., std::unordered_map< LAMMPS_NS::tagint parent_atomID , std::vector< PAPRECA::Bond > >). The atomID2bonds container provides direct access to all the bonds of the parent atom.

See also: PAPRECA::deleteDesorbedAtoms(), PAPRECA::Bond::recursiveCollectBondedAtoms()

Note: When deleting an atom, all atoms bonded with the deleted atom have to be deleted as well. Otherwise, LAMMPS will likely throw a "Missing Bond Atoms in proc %d" error. See lammps documentation (https://docs.lammps.org/) for more information.; This function is not to be confused with fillDelidsVec(). fillDelidsVec() is only called when the user sets the delete_desorbed algorithm to gather_all, while this function (i.e., fillDelidsLocalVec() ) is called if the user set the delete_desorbed algorithm to gather_local.

◆ fillDelidsVec()

int PAPRECA::fillDelidsVec	(	LAMMPS_NS::LAMMPS *	lmp,
		const int &	proc_id,
		const double &	desorb_cut,

		ATOM2BONDS_MAP &	atomID2bonds
	)

Called by deleteDesorbedAtoms() and only when the delete_desorbed algorithm is set to gather_all. The function compares the z-coordinate of an atom. If the atom z-coordinate is higher than desorb_cut, the atom ID is marked for deletion (i.e., inserted in the delids container) and it is deleted along with its bonded atoms (retrieved from atomID2bonds map). Here, a gather operation collects data from all atoms on the master MPI process (i.e., proc_id==0) before comparing the z-coordinates of atoms with desorb_cut.

Parameters

[in]	lmp	pointer to LAMMPS object.
[in]	proc_id	ID of current MPI process.
[in]	desorb_cut	cutoff distance for atom deletion. Atoms whose z-coordinate is equal to or greater than desorb_cut are marked for deletion.
[in,out]	delids	vector of collected atom IDs on the master MPI process.
[in]	atomID2bonds	PAPRECA::ATOM2BONDS_MAP container (i.e., std::unordered_map< LAMMPS_NS::tagint parent_atomID , std::vector< PAPRECA::Bond > >). The atomID2bonds container provides direct access to all the bonds of the parent atom.

		const int &	nprocs,
		std::vector< LAMMPS_NS::tagint > &	delids_local,
		std::vector< LAMMPS_NS::tagint > &	delids_global
	)

Called by deleteDesorbedAtoms() and only when the delete_desorbed algorithm is set to gather_local.

Then, the function fills delids_global with the IDs of all atoms marked for deletion and makes sure that no duplicate deletions are performed.

Parameters

[in]	proc_id	ID of current MPI process.
[in]	nprocs	number of MPI processes.
[in]	delids_local	contains the IDs of atoms marked for deletion on a specific MPI process (i.e., the delids_local container is different on each MPI process).
[in,out]	delids_global	vector containing the IDs of all atoms marked for deletion (contains the same data on each MPI process as casted from the master process).

See also: PAPRECA::deleteDesorbedAtoms(), PAPRECA::fillDelidsLocalVec()

		PaprecaConfig &	papreca_config,
		double *	iatom_xyz,
		double *	candidate_xyz,
		PredefinedDeposition *	depo_template
	)

Fills candidate_xyz array with the coordinates of the deposition candidate. The deposition candidate coordinates DO NOT coincide with the parent atom coordinates. Depending on the user input settings in PAPRECA input, the deposition candidate coordinates can either be directly above the parent atom or on the surface of the upper hemisphere centered at the parent atom coordinates.

Parameters

[in]	lmp	pointer to LAMMPS object.
[in]	papreca_config	object of the PAPRECA::PaprecaConfig class that stores global variables and settings for the current PAPRECA run.

Hence, you cannot get a film growing towards -z.; The user is given the chance to produce a point at a random position on the surface of a sphere and at a distance equal to depo_offset. depo_offset is defined as the offset distance for the deposition event (using the create_Deposition command in the PAPRECA input file). Here, we use the random number generator (on the parent event proc) to generate 2 random numbers. Those 2 random numbers are used to generate a random vector on a sphere with a radius of depo_offset around the parent atom.

◆ loopAtomsAndIdentifyEvents()

		std::vector< Event * > &	events_local,
		ATOM2BONDS_MAP &	atomID2bonds,
		double &	film_height
	)

1) Calculates film height (if that is requested by the user). 2) Discovers events and inserts them in the PAPRECA::Event objects vector (storing all events detected on the current MPI process). PAPRECA::BondBreak, PAPRECA::Deposition, PAPRECA::MonoatomicDesorption, and PAPRECA::Diffusion are discovered through a full neighbors list. PAPRECA::BondForm are detected using a half-neighbors list. This is done because bondbreak, deposition, monoatomic desorption, and diffusion events perform collision checks which require full neighbor lists (because we need to know all the neighbors of each atom). On the other hand, it is more efficient to check for PAPRECA:BondForm events using a half neighbors list that include each neighbor pair once.

Parameters

[in]	lmp	pointer to LAMMPS object.
[in]	proc_id	ID of current MPI process.
[in]	nprocs	total number of MPI processes.
[in]	KMC_loopid	current PAPRECA step.

[in,out]	events_local	vector containing all the PAPRECA::Event objects for a specific MPI process.
[in]	atomID2bonds	PAPRECA::ATOM2BONDS_MAP container (i.e., std::unordered_map< LAMMPS_NS::tagint parent_atomID , std::vector< PAPRECA::Bond > >). The atomID2bonds container provides direct access to all the bonds of the parent atom.
[in,out]	film_height	film height at current PAPRECA step.

In the end, all MPI processes initialize an identical copy of PAPRECA::PaprecaConfig (containing the settings and global variables for the PAPRECA run).

Parameters

[in]	lmp	pointer to previously instantiated LAMMPS object.
[in]	proc_id	ID of current MPI process.
[in]	file_name	name of PAPRECA input file.
[in,out]	papreca_config	previously instantiated PAPRECA::PaprecaConfig object storing the settings and global variables for the PAPRECA simulation.

Note: After initializing the PAPRECA::PaprecaConfig object in all procs, this function warns for or aborts illegal runs.

◆ readLMPinput()

void PAPRECA::readLMPinput	(	const std::string &	lmp_input,
		LAMMPS_NS::LAMMPS *	lmp
	)

Reads LAMMPS input and initializes LAMMPS parameters.

Parameters

[in]	lmp_input	name of LAMMPS input file (command-line argument).
[in,out]	lmp	pointer to LAMMPS object.

◆ remap3DArrayInPeriodicBox()

void PAPRECA::remap3DArrayInPeriodicBox	(	LAMMPS_NS::LAMMPS *	lmp,
		double *	arr
	)

Receives an 1D array of 3 elements (i.e., x,y, and z coordinates) and remaps it inside the existing periodic box (as set in the provided LAMMPS object).

Parameters

[in]	lmp	pointer to previously instantiated LAMMPS object.
[in]	arr	array of coordinates.

Note: See domain.h header for more information about the domain->remap function.

◆ resetMobileAtomsGroups()

void PAPRECA::resetMobileAtomsGroups	(	LAMMPS_NS::LAMMPS *	lmp,
		const std::vector< int > &	fluid_atomtypes
	)

Clears the fluid group (containing the fluid atom types, as defined in the PAPRECA input file) and redefines it to. This ensures that all atoms of fluid types are included in the fluid group.

Parameters

[in,out]	lmp	pointer to previously instantiated LAMMPS object.
[in]	fluid_atomtypes	vector containing the fluid atom types.

Note: This function is a wrapper of this LAMMPS command: https://docs.lammps.org/group.html.; This operation is necessary each time you add/remove atoms. This ensures that the correct group of atoms will keep moving in the simulation.

◆ runLammps()

void PAPRECA::runLammps	(	LAMMPS_NS::LAMMPS *	lmp,
		const int &	timesteps_num
	)

Runs LAMMPS trajectory for given (previously initialized) LAMMPS object.

Parameters

[in,out]	lmp	pointer to previously instantiated LAMMPS object.
[in]	timesteps_num	number of timesteps to execute.

Note: This function is a wrapper of this LAMMPS command: https://docs.lammps.org/run.html

◆ selectAndExecuteEvent()

int PAPRECA::selectAndExecuteEvent	(	LAMMPS_NS::LAMMPS *	lmp,
		int &	KMC_loopid,
		double &	time,
		char *	event_type,
		int &	proc_id,
		int &	nprocs,
		PaprecaConfig &	papreca_config,
		std::vector< Event * > &	events_local,
		ATOM2BONDS_MAP &	atomID2bonds,
		double &	film_height
	)

Gets total event rate by gathering all local rates (i.e., sum of rates on a single MPI process). Then, selects an event MPI process using the N-FOLD way. Afterwards, an event is chosen from the selected MPI process and executed on all procs.

Parameters

[in,out]	lmp	pointer to LAMMPS object.
[in]	KMC_loopid	current PAPRECA step.
[in,out]	time	current time.
[in,out]	event_type	type of selected event.
[in]	proc_id	ID of current MPI process.
[in]	nprocs	total number of MPI processes.
[in]	papreca_config	object of the PAPRECA::PaprecaConfig class that stores global variables and settings for the current PAPRECA run.
[in]	events_local	vector containing all the PAPRECA::Event objects for a specific MPI process.
[in]	atomID2bonds	PAPRECA::ATOM2BONDS_MAP container (i.e., std::unordered_map< LAMMPS_NS::tagint parent_atomID , std::vector< PAPRECA::Bond > >). The atomID2bonds container provides direct access to all the bonds of the parent atom.
[in]	film_height	current height.

Note: Currently, we discover events on all MPI processes. However, KMC events are not executed in parallel as only one event from one MPI processes is fired at a time. We plan to introduce parallel event execution in subsequent versions of PAPRECA. Additional code will have to be written to prevent errors in neighboring events (e.g., execution of 2 deposition events that overlap, breaking of the same bond twice, etc.). Of course, executing events in parallel is expected to elevate the scalability and boost the efficiency of the code even further.; See this paper for more information regarding the classic N-FOLD way and the selection of events: https://www.sciencedirect.com/science/article/pii/S0927025623004159

◆ selectProcessStochastically()

int PAPRECA::selectProcessStochastically	(	double *	arr,
		const int &	arr_size,
		double &	rnum,
		double &	rates_sum
	)

Selects a process stochastically (through the classic N-FOLD way selection process). Can be used to select an MPI proc that fires an event or can be used to select the next kMC event inside the proc. The event selection is performed on a std::vector< std::pair< double , int > > container that holds the rate and the associated index of events.

Parameters

[in]	arr	array of rates.
[in]	arr_size	size of arr.
[in]	rnum	uniformly distributed (between 0 and 1) pseudorandom number (usually drawn on master proc).
[in]	rates_sum	total sum of rates

Returns: integer that corresponds to the ith position of the provided vector (i.e., index of the selected process) or -1 if the function could not select a process (indicates error).

See also: PAPRECA::selectAndExecuteEvent()

Note: See paper and equation 3 here for more information regarding the classic N-FOLD way and the event selection process: https://www.sciencedirect.com/science/article/pii/S0927025623004159

◆ setTimeUnitsConversionConstant()

void PAPRECA::setTimeUnitsConversionConstant	(	LAMMPS_NS::LAMMPS *	lmp,
		PaprecaConfig &	papreca_config
	)

Retrieves the LAMMPS units style from the provided LAMMPS object (lmp) and sets the conversion time variable of the PAPRECA::PaprecaConfig object.

Parameters

[in]	lmp	pointer to previously instantiated LAMMPS object.
[in,out]	papreca_config	previously instantiated PAPRECA::PaprecaConfig object storing the settings and global variables for the PAPRECA simulation.

Note: This operation is necessary, since PAPRECA will always report time in seconds (SI units), regardless of the LAMMPS time units. Any other variable in PAPRECA (e.g., length) has units consistent with LAMMPS units.

◆ setupMPI()

void PAPRECA::setupMPI	(	int *	narg,
		char ***	arg,
		int *	nprocs,
