Detailed Description

Access material properties.

A material is a combination of nuclides/elements at a particular state (e.g. density, temperature). The proportions and identities of a material's constituents are encoded in the elements accessor, where each index of the returned span corresponds to an ElementComponentId for this material. The get_element_density and element_view helper functions can be used to calculate elemental densities and properties.

Member Function Documentation

element_record()

CELER_FUNCTION ElementView celeritas::MaterialView::element_record ( ElementComponentId  id ) const

inline

Get element properties from a material-specific index.

Todo:

Rename element

optical_material_id()

CELER_FUNCTION OptMatId celeritas::MaterialView::optical_material_id

(

)

const

Get the index in the optical properties for this material.

This will return a null ID if the material has no optical properties attached.

zeff()

CELER_FUNCTION real_type celeritas::MaterialView::zeff ( ) const

inline

Weighted atomic number.

This is Z weighted by the atomic fraction of each element in the material.
