Public Functions

explicit ElasticityFreqProblemParameters(const std::string &subsection = "/Immersed Problem/", std::vector<double> *shared_frequencies = nullptr)

Build and register all parameter subsections used by the elasticity model.

A shared frequency vector is registered by its owner and must outlive this parameter object.

const MaterialProperties &get_material_properties(const types::material_id material_id) const

Return material parameters associated with a material id.

const ModulatedParsedFunction<spacedim> &get_dirichlet_bc(const types::boundary_id boundary_id) const

const ModulatedParsedFunction<spacedim> &get_neumann_bc(const types::boundary_id boundary_id) const

const Functions::ParsedFunction<spacedim> &get_robin_coefficient(const types::boundary_id boundary_id) const

const ModulatedParsedFunction<spacedim> &get_robin_bc(const types::boundary_id boundary_id) const

const ModulatedParsedFunction<spacedim> &get_rhs(const types::material_id material_id) const

void set_rhs_times(const double time) const

void set_boundary_condition_times(const double time) const

void validate_parameters()

Validate boundary and material data after parameter parsing.
