Constructor & Destructor Documentation

◆ Environment()

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

Constructor.

Parameters
argc,argvIf 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 ( )
