specfem::medium::material< dim2, acoustic, isotropic >

template<specfem::dimension::type DimensionTag>
class material<DimensionTag, specfem::element::medium_tag::acoustic, specfem::element::property_tag::isotropic>

Template specialization for acoustic isotropic material properties.

Constructors

inline material(const type_real &density, const type_real &cp, const type_real &Qkappa, const type_real &Qmu, const type_real &compaction_grad)

Construct a new acoustic isotropic material.

Parameters:

• density – Density of the material

• cp – Compressional wave speed

• Qkappa – Attenuation factor for bulk modulus

• Qmu – Attenuation factor for shear modulus

• compaction_grad – Compaction gradient

inline bool operator==(const material<dimension_tag, specfem::element::medium_tag::acoustic, specfem::element::property_tag::isotropic> &other) const

Check if 2 materials have the same properties.

Parameters:

other – Material to compare with

Returns:

true If the materials have the same properties

inline bool operator!=(const material<dimension_tag, specfem::element::medium_tag::acoustic, specfem::element::property_tag::isotropic> &other) const

Check if 2 materials have different properties.

Parameters:

other – Material to compare with

Returns:

true If the materials have different properties

material() = default

Default constructor.

Public Functions

Get the properties of the material.

Returns:

specfem::point::properties Material properties

inline std::string print() const

Print the material properties.

Returns:
