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 (that is, ";" 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 three different types of input files within Cantera. The YAML format is new in Cantera 2.5, and replaces both the CTI and CTML (XML) formats, which are deprecated and will be removed in Cantera 3.0. The scripts cti2yaml.py and ctml2yaml.py can be used to convert legacy input files to the YAML format.

YAML: A human-readable input file written using YAML syntax which defines species, phases, and reactions, and contains thermodynamic, chemical kinetic, and transport data needed by Cantera.
CTI: A human-readable input file written using Python syntax. Some options for non-ideal equations of state available in the CTML format have not 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.

Cantera provides converters (ck2yaml and ckcti) for converting Chemkin-format mechanisms to the YAML and CTI formats, respectively.

◆ 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 first directory searched is usually the current working directory.

The default set of directories will not be searched if an absolute path (for example, one starting with / or C:\) or a path relative to the user's home directory (for example, starting with ~/) is specified.

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

If the file is not found a CanteraError exception is thrown.

◆ addDirectory()

void addDirectory ( 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 155 of file global.cpp.

References Application::addDataDirectory(), and Cantera::app().

◆ getDataDirectories() [1/2]

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

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

Definition at line 160 of file global.cpp.

References Cantera::app(), and Application::getDataDirectories().

◆ canteraRoot()

string canteraRoot ( )

Returns root directory where Cantera is installed.

Returns: a string containing the name of the base directory where Cantera is installed. If the environmental variable CANTERA_ROOT is defined, this function will return its value, preferentially.

Deprecated:: Unused within Cantera. To be removed after Cantera 2.6

Definition at line 190 of file global.cpp.

◆ 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)

Deprecated:: The XML input format is deprecated and will be removed in Cantera 3.0.

◆ 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.

Deprecated:: The XML input format is deprecated and will be removed in Cantera 3.0.

The default set of directories will not be searched if an absolute path (for example, one starting with / or C:\) or a path relative to the user's home directory (for example, starting with ~/) is specified.

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

◆ getDataDirectories() [2/2]

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.
