Detailed Description

Shared model parameters for a VecGeom geometry.

The model defines the shapes, volumes, etc.

Constructor & Destructor Documentation

VecgeomParams()

celeritas::VecgeomParams::VecgeomParams	(	vecgeom::GeoManager const &	geo,
		Ownership	owns,
		VecLv const &	lv,
		VecPv &&	pv
	)

Set up vecgeom given existing an already set up VecGeom CPU world.

Todo:

we still need to make volume tracking information when using CUDA, because we need a GPU world device pointer. We could probably just make a single world physical/logical volume that have the correct IDs.

Member Function Documentation

bbox()

BBox const & celeritas::VecgeomParams::bbox ( ) const

inlinefinalvirtual

Outer bounding box of geometry.

Implements celeritas::GeoParamsInterface.

device_ref()

DeviceRef const & celeritas::VecgeomParams::device_ref ( ) const

inlinefinalvirtual

Access geometry data on device.

Implements celeritas::ParamsDataInterface< VecgeomParamsData >.

find_volume() [1/2]

VolumeId celeritas::VecgeomParams::find_volume ( G4LogicalVolume const *  volume ) const

finalvirtual

Locate the volume ID corresponding to a Geant4 logical volume.

Implements celeritas::GeoParamsInterface.

find_volume() [2/2]

virtual VolumeId celeritas::GeoParamsInterface::find_volume ( G4LogicalVolume const *  volume ) const

virtual

Get the volume ID corresponding to a Geant4 logical volume.

Implements celeritas::GeoParamsInterface.

from_gdml_g4()

std::shared_ptr< VecgeomParams > celeritas::VecgeomParams::from_gdml_g4 ( std::string const &  filename )

static

Build by loading a GDML file using Geant4.

This mode is incompatible with having an existing run manager. It will clear the geometry once complete.

host_ref()

HostRef const & celeritas::VecgeomParams::host_ref ( ) const

inlinefinalvirtual

Access geometry data on host.

Implements celeritas::ParamsDataInterface< VecgeomParamsData >.

id_to_geant()

GeantPhysicalInstance celeritas::VecgeomParams::id_to_geant ( VolumeInstanceId  vol_id ) const

finalvirtual

Get the Geant4 physical volume corresponding to a volume instance ID.

Implements celeritas::GeoParamsInterface.

make_model_input()

inp::Model celeritas::VecgeomParams::make_model_input ( ) const

finalvirtual

Create model parameters corresponding to our internal representation.

This could be used to eliminate the "gaps" from the [TEMP] volumes.

Implements celeritas::GeoParamsInterface.

max_depth()

LevelId::size_type celeritas::VecgeomParams::max_depth ( ) const

inlinefinalvirtual

Maximum nested geometry depth.

Todo:

move to VolumeParams

Implements celeritas::GeoParamsInterface.

supports_safety()

bool celeritas::VecgeomParams::supports_safety ( ) const

inlinefinalvirtual

Whether safety distance calculations are accurate and precise.

Implements celeritas::GeoParamsInterface.

volume_instances()

auto celeritas::VecgeomParams::volume_instances ( ) const

inlinefinalvirtual

Get volume instance metadata.

Volume instances correspond directly to Geant4 physical volumes.

Implements celeritas::GeoParamsInterface.

volumes()

auto celeritas::VecgeomParams::volumes ( ) const

inlinefinalvirtual

Get volume metadata.

Implements celeritas::GeoParamsInterface.
