Public Attributes
Volume-to-universe conversion
unsigned int	explicit_interior_threshold {2}
	Volumes with up to this many children construct an explicit interior.

bool	inline_childless {true}
	Forcibly inline volumes that have no children.

InlineSingletons	inline_singletons {InlineSingletons::untransformed}
	Forcibly inline volumes that are only used once.

bool	inline_unions {true}
	Forcibly copy child volumes that have union boundaries.

std::map< std::string, SquareMatrixReal3 >	universe_alignment
	Rotation matrices that makes the daughters within LVs axis-aligned, to improve acceleration.

unsigned int	align_daughter_threshold {10}
	The minimum number of daughters required for an LV to be a candidate for automatic alignment (zero disables).

double	align_daughter_fraction {0.8}
	Fraction of daughters that must share a rotation to automatically align an LV.

Debug output
bool	verbose_volumes {false}
	Write output about volumes being converted.

bool	verbose_structure {false}

	Helper to write the options to a file or stream.

Detailed Description

Construction options for Geant4 conversion.

Note that most of these should never be touched when running an actual problem. If the length unit is changed, the resulting geometry is inconsistent with Geant4's scale.

Member Data Documentation

◆ align_daughter_fraction

double celeritas::inp::OrangeGeoFromGeant::align_daughter_fraction {0.8}

Fraction of daughters that must share a rotation to automatically align an LV.

Must be > 0.5.

◆ align_daughter_threshold

unsigned int celeritas::inp::OrangeGeoFromGeant::align_daughter_threshold {10}

The minimum number of daughters required for an LV to be a candidate for automatic alignment (zero disables).

This requirement is bypassed for LVs that are entries in the user-supplied universe_alignment map.

◆ universe_alignment

std::map<std::string, SquareMatrixReal3> celeritas::inp::OrangeGeoFromGeant::universe_alignment

Rotation matrices that makes the daughters within LVs axis-aligned, to improve acceleration.

Keys are LV names.
