getTree()

static const LoggingParameterTree & Dumux::Parameters::getTree ( )

inlinestatic

Get the parameter tree.

The logging parameter tree recording which parameters are used during the simulation

init() [1/6]

static void Dumux::Parameters::init ( const DefaultParams &  params = [] (Dune::ParameterTree&) {}, const DefaultParams &  defaultParams = [] (Dune::ParameterTree&) {}  )

inlinestatic

Initialize the parameter tree.

Parameters

params	a function that sets parameters of the runtime parameter tree
defaultParams	a function that sets parameters of the default runtim parameter tree

Note

if a parameter is looked up without explicitly providing a default, the default tree is consulted if the parameter could not be found in the parameter tree

init() [2/6]

static void Dumux::Parameters::init ( const std::string &  parameterFileName, const DefaultParams &  params = [] (Dune::ParameterTree&) {}, bool  inputFileOverwritesParams = true, const DefaultParams &  defaultParams = [] (Dune::ParameterTree&) {}  )

inlinestatic

Initialize the parameter tree.

Parameters

parameterFileName	an input parameter file name
params	a parameter tree with runtime parameters
inputFileOverwritesParams	if set to true (default) the parameters from the input file have precedence, if set to false the input the parameters provided via params have precedence
defaultParams	a parameter tree with default parameters

Note

the params function overwrites

if a parameter is looked up without explicitly providing a default, the default tree is consulted if the parameter could not be found in the parameter tree

init() [3/6]

static void Dumux::Parameters::init ( int  argc, char **  argv, const DefaultParams &  defaultParams, const Usage &  usage  )

inlinestatic

Initialize the parameter tree singletons.

init() [4/6]

static void Dumux::Parameters::init ( int  argc, char **  argv, const DefaultParams &  defaultParams = [] (Dune::ParameterTree&) {}, std::string  parameterFileName = "", const Usage &  usage = [](const char *, const std::string &){}  )

inlinestatic

Initialize the parameter tree.

Parameters

argc	number of command line argument (forwarded from main)
argv	command line argument (forwarded from main)
defaultParams	a function that sets parameters of the default runtime parameter tree
parameterFileName	the file name of the input file
usage	the usage function to print if the help option was passed on the command line

Note

the default parameter tree is initialized in the following way 1) global defaults (see member function applyGlobalDefaults_) 2) user provided defaults (overwrite global defaults) the parameter tree is initialized in the following way 1) parameters from the input file 2) parameters from the command line (overwrite input file parameters)

if a parameter is looked up without explicitly providing a default, the default tree is consulted if the parameter could not be found in the parameter tree

init() [5/6]

static void Dumux::Parameters::init ( int  argc, char **  argv, const Usage &  usage  )

inlinestatic

Initialize the parameter tree singletons.

init() [6/6]

static void Dumux::Parameters::init ( int  argc, char **  argv, std::string  parameterFileName, const Usage &  usage = [](const char *, const std::string &){}  )

inlinestatic

Initialize the parameter tree singletons.

parseCommandLine()

static Dune::ParameterTree Dumux::Parameters::parseCommandLine ( int  argc, char **  argv  )

inlinestatic

Parse command line arguments into a parameter tree.

print()

static void Dumux::Parameters::print ( )

inlinestatic

prints all used and unused parameters
