Constructor & Destructor Documentation

◆ Environment()

walberla::Environment::Environment	(	int &	argc,
		char **&	argv,
		bool	mpiAbortOnException = true )

Constructor.

Parameters

argc,argv If command line parameters are present they have to contain at least the path to the configuration file and optionally pairs of param-value: "-blockName.parameterName=parameterValue" These values are then substituted in configuration files. It is also possible to pass no command line options (see description below )

If command line arguments are present the constructor initializes static objects and singleton classes using information of configuration file

MPIManager ( via mpi::Environment )
reads configuration file
configures Logging

If no command line arguments are present only MPI subsystem is initialized and logging is configured to default state.

◆ ~Environment()

walberla::Environment::~Environment ( )

Member Function Documentation

◆ config()

shared_ptr< Config > walberla::Environment::config ( )

inline

Returns configuration object, or null if no configuration object exists.

Returns: handle to configuration object, if a path to configuration file was in the command line arguments as passed to constructor, otherwise a null pointer
