Detailed Description

structure in charge of handling the state of a material in an optimized way. Here, the "material" is defined by a behaviour and a number of integration points.

The following design choices were made:

• The material properties and the external state variables are treated individually. They can be uniform or spatially variable.
• The internal state variables are treated as a block.

Member Data Documentation

external_state_variables

std::map<std::string, FieldHolder, std::less<> > mgis::behaviour::MaterialStateManager::external_state_variables

values of the external state variables

The external state variables can be uniform or not. In the non uniform case, the data can be hold by the structure (std::vector<real>) or simply borrow a reference (std::span<mgis::real> case).

EXTERNAL_STORAGE

constexpr auto mgis::behaviour::MaterialStateManager::EXTERNAL_STORAGE

staticconstexpr

Initial value:

=
        mgis::StorageMode::EXTERNAL_STORAGE

internal_state_variables_stride

const size_type mgis::behaviour::MaterialStateManager::internal_state_variables_stride

stride associate with internal state variables.

Note

this is also the size of an array containing all the internal state variables for one integration point.

mass_density

std::optional<MutableFieldHolder> mgis::behaviour::MaterialStateManager::mass_density

mass density

The mass density can be uniform or not. In the non uniform case, the data can be hold by the structure (std::vector<real>) or simply borrow a reference (std::span<mgis::real> case).

material_properties

std::map<std::string, FieldHolder, std::less<> > mgis::behaviour::MaterialStateManager::material_properties

material properties

The material properties can be uniform or not. In the non uniform case, the data can be hold by the structure (std::vector<real>) or simply borrow a reference (std::span<mgis::real> case).
