Constructor & Destructor Documentation

Phreeqc()

Phreeqc

(

String

database

)

Construct a Phreeqc instance with given PHREEQC database.

Parameters

database

The name of the database file

Member Function Documentation

set() [1/2]

auto set	(	double	T,
		double	P
	)		-> void

Set the temperature and pressure of the interfaced code.

This method should be used to update all thermodynamic properties that depend only on temperature and pressure, such as standard thermodynamic properties of the species.

Parameters

T	The temperature (in units of K)
P	The pressure (in units of Pa)

set() [2/2]

auto set	(	double	T,
		double	P,
		ArrayXdConstRef	n
	)		-> void

Set the temperature, pressure and species composition of the interfaced code.

This method should be used to update all thermodynamic properties that depend only on temperature and pressure, such as standard thermodynamic properties of the species, as well as chemical properties that depend on the composition of the species.

Parameters

T	The temperature (in units of K)
P	The pressure (in units of Pa)
n	The composition of the species (in units of mol)

load()

auto load

(

String

database

)

-> void

Load a PHREEQC database.

This method will initialize the Phreeqc instance with all species and reactions found in the given database. To execute a Phreeqc script file, check the execute method.

See also

execute

Parameters

database

The path to the database file.

execute() [1/2]

auto execute	(	String	input,
		String	output
	)		-> void

Execute a PHREEQC input script either provided as a file or input string.

This method will execute the given PHREEQC input script and put this Phreeqc instance in a state with active species and phases from the last PHREEQC calculation specified in the script file. This can then be used to initialize a ChemicalSystem instance with such configuration.

Parameters

input	The input either as a filename or as an input script coded in a string.
output	The name of the file where the result should be output

execute() [2/2]

auto execute

(

String

input

)

-> void

Execute a PHREEQC input script either provided as a file or input string.

Parameters

input

The input either as a filename or as an input script coded in a string.

reset()

auto reset

(

)

-> void

Reset this Phreeqc instance to a clean state.

After this Phreeqc instance is reset, one must again load a new database and execute a new input script file.
