Function Documentation

find_geant_volumes()

std::unordered_set< G4LogicalVolume const * > celeritas::find_geant_volumes ( std::unordered_set< std::string >  names )

inline

Find Geant4 logical volumes corresponding to a list of names.

If logical volumes with duplicate names are present, they will all show up in the output and a warning will be emitted. If one is missing, a RuntimeError will be raised.

static std::string_view const labels[] = {"Vol1", "Vol2"};
auto vols = find_geant_volumes(make_span(labels));

geant_field()

G4Field const * celeritas::geant_field

(

)

Get an optional global magnetic field for the tracking geometry.

Returns

Field if geometry has been initialized and field exists, nullptr otherwise.

geant_logical_volumes()

Span< G4LogicalVolume * > celeritas::geant_logical_volumes ( )

inline

Get a view to the Geant4 LV store.

This includes all volumes, potentially null ones as well.

geant_world_volume()

G4VPhysicalVolume const * celeritas::geant_world_volume

(

)

Get the world volume for the primary geometry.

Returns

World volume if geometry has been initialized, nullptr otherwise.

operator<<()

std::ostream & celeritas::operator<< ( std::ostream &  os, StreamableNavHistory const &  pnh  )

inline

Print detailed information about the touchable history.

For brevity, this does not print the world volume.

reset_geant_geometry()

void celeritas::reset_geant_geometry ( )

inline

Reset all Geant4 geometry stores if not using RunManager.

Use this function if reading geometry and cleaning up without doing any transport in between (useful for geometry conversion testing).
