Member Function Documentation

operator()()

template<typename LocalAssemblerInterface, NumLib::IntegrationMethodProvider IntegrationMethodProvider, typename... ConstructorArgs>

LocAsmIntfPtr ProcessLib::GenericLocalAssemblerFactory< LocalAssemblerInterface, IntegrationMethodProvider, ConstructorArgs >::operator() ( std::size_t const id, MeshLib::Element const & mesh_item, ConstructorArgs &&... args ) const

inline

Returns the newly created local assembler.

Attention

The index id is not necessarily the mesh item's id. Especially when having multiple meshes it will differ from the latter.
