Detailed Description

The properties of phases and interfaces are specified in text files. These procedures handle various aspects of reading these files.

For input files not specified by an absolute pathname, Cantera searches for input files along a path that includes platform-specific default locations, and possibly user-specified locations.

The current directory (".") is always searched first. Then, on Windows, the registry is checked to find the Cantera installation directory, and the 'data' subdirectory of the installation directory will be added to the search path.

On the Mac, directory '/Applications/Cantera/data' is added to the search path.

On any platform, if environment variable CANTERA_DATA is set to a directory name or a list of directory names separated with the OS-dependent path separator (i.e. ";" on Windows, ":" elsewhere), then these directories will be added to the search path.

Finally, the location where the data files were installed when Cantera was built is added to the search path.

Additional directories may be added by calling function addDirectory.

There are currently two different types of input files within Cantera:

CTI: A human-readable input file written using Python syntax which defines species, phases, and reactions, and contains thermodynamic, chemical kinetic, and transport data needed by Cantera. Some options for non-ideal equations of state available in the CTML format have not yet been implemented for the CTI format.
CTML: This is an XML file laid out in such a way that Cantera can interpret the contents directly. Given a file in CTI format, Cantera will convert the CTI file into the CTML format on-the-fly using a Python script (ctml_writer). This process is done in-memory without writing any new files to disk. Explicit use of the CTML format is not recommended unless using features not available in CTI or working on a computer where Python is not available.

Cantera provides a converter (ck2cti) for converting Chemkin-format gas-phase mechanisms to the CTI format.

Function Documentation

◆ addDataDirectory()

void addDataDirectory ( const std::string & dir )

Add a directory to the data file search path.

Parameters

dir	String name for the directory to be added to the search path

Definition at line 374 of file application.cpp.

References Cantera::dir_mutex, Application::inputDirs, and Application::setDefaultDirectories().

Referenced by Cantera::addDirectory().

◆ findInputFile() [1/2]

std::string findInputFile ( const std::string & name )

Find an input file.

This routine will search for a file in the default locations specified for the application. See the routine setDefaultDirectories() listed above.

The default set of directories specified for the application will be searched if a '/' or an '\' is not found in the name. If either is found then a relative path name is presumed, and the default directories are not searched.

The presence of the file is determined by whether the file can be opened for reading by the current user.

Parameters

name	Name of the input file to be searched for

Returns: The absolute path name of the first matching file is returned. If a relative path name is indicated, the relative path name is returned.

If the file is not found, a message is written to stdout and a CanteraError exception is thrown.

◆ getDataDirectories() [1/2]

std::string getDataDirectories ( const std::string & sep )

inline

Get the Cantera data directories.

This routine returns a string including the names of all the directories searched by Cantera for data files.

Parameters

sep	Separator to use between directories in the string

Returns: A string of directories separated by the input sep

◆ setDefaultDirectories()

void setDefaultDirectories ( )

protected

Set the default directories for input files.

Cantera searches for input files along a path that includes platform- specific default locations, and possibly user-specified locations. This function installs the platform-specific directories on the search path. It is invoked at startup by appinit(), and never should need to be called by user programs.

The current directory (".") is always searched first. Then, on Windows platforms, if environment variable COMMONPROGRAMFILES is set (which it should be on Win XP or Win 2000), then directories under this one will be added to the search path. The Cantera Windows installer installs data files to this location.

On the Mac, directory '/Applications/Cantera/data' is added to the search path.

On any platform, if environment variable CANTERA_DATA is set to a directory name, then this directory is added to the search path.

Finally, the location where the data files were installed when Cantera was built is added to the search path.

Additional directories may be added by calling function addDirectory.

◆ ct2ctml()

void ct2ctml	(	const char *	file,
		const int	debug = `0`
	)

Convert a cti file into a ctml file.

Parameters

debug	Turn on debug printing

◆ ct2ctml_string()

std::string ct2ctml_string ( const std::string & file )

Get a string with the ctml representation of a cti file.

Parameters

file	Path to the input file in CTI format

Returns: String containing the XML representation of the input file

◆ ct_string2ctml_string()

std::string ct_string2ctml_string ( const std::string & cti )

Get a string with the ctml representation of a cti input string.

Parameters

◆ findInputFile() [2/2]

std::string findInputFile ( const std::string & name )

Find an input file.

This routine will search for a file in the default locations specified for the application. See the routine setDefaultDirectories() listed above.

The default set of directories specified for the application will be searched if a '/' or an '\' is not found in the name. If either is found then a relative path name is presumed, and the default directories are not searched.

The presence of the file is determined by whether the file can be opened for reading by the current user.

Parameters

name	Name of the input file to be searched for

Returns: The absolute path name of the first matching file is returned. If a relative path name is indicated, the relative path name is returned.

Parameters

◆ getDataDirectories() [2/2]

std::string getDataDirectories ( const std::string & sep )

◆ canteraRoot()

◆ buildSolutionFromXML()

bool buildSolutionFromXML	(	XML_Node &	root,
		const std::string &	id,
		const std::string &	nm,
		ThermoPhase *	th,
		Kinetics *	kin
	)

Build a single-phase ThermoPhase object with associated kinetics mechanism.

In a single call, this routine initializes a ThermoPhase object and a homogeneous kinetics object for a phase. It returns the fully initialized ThermoPhase object pointer and kinetics pointer.

Parameters

root	pointer to the XML tree which will be searched to find the XML phase element.
id	Name of the phase to be searched for.
nm	Name of the XML element. Should be "phase"
th	Pointer to a bare ThermoPhase object, which will be initialized by this operation.
kin	Pointer to a bare Kinetics object, which will be initialized by this operation to a homogeneous kinetics manager

Returns: Returns true if all went well. If there are errors, it will return false.

For Example

ThermoPhase *th   = new ThermoPhase();
Kinetics    *kin  = new Kinetics();
XML_Node *root = get_XML_File("gri30.xml");
ok =  buildSolutionFromXML(root, "gri30_mix", "phase", th, kin)

◆ newPhase()

ThermoPhase * newPhase ( XML_Node & phase )

Create a new ThermoPhase object and initializes it according to the XML tree.

This routine first looks up the identity of the model for the solution thermodynamics in the model attribute of the thermo child of the XML phase node. Then, it does a string lookup using Cantera's internal ThermoPhase Factory routines on the model to figure out what ThermoPhase derived class should be assigned. It creates a new instance of that class, and then calls importPhase() to populate that class with the correct parameters from the XML tree.

Parameters

phase XML_Node reference pointing to the phase XML element.

Returns: A pointer to the completed and initialized ThermoPhase object.
