Detailed Description

template<int dim>
class aspect::MaterialModel::Nondimensional< dim >

A material model for incompressible (using the Boussinesq approximation) and compressible computations (with ALA or TALA) for a nondimensionalized problem. The viscosity is (optionally) depth and temperature dependent.

Definition at line 42 of file nondimensional.h.

Member Function Documentation

§ initialize()

template<int dim>
virtual void aspect::MaterialModel::Nondimensional< dim >::initialize ( )
virtual

Initialize.

Reimplemented from aspect::MaterialModel::Interface< dim >.

§ evaluate()

template<int dim>
virtual void aspect::MaterialModel::Nondimensional< dim >::evaluate ( const MaterialModel::MaterialModelInputs< dim > &  in,
MaterialModel::MaterialModelOutputs< dim > &  out 
) const
virtual

Evaluate the material model.

Implements aspect::MaterialModel::Interface< dim >.

§ is_compressible()

template<int dim>
virtual bool aspect::MaterialModel::Nondimensional< dim >::is_compressible ( ) const
virtual

Return whether the model is compressible or not.

Implements aspect::MaterialModel::Interface< dim >.

§ reference_viscosity()

template<int dim>
virtual double aspect::MaterialModel::Nondimensional< dim >::reference_viscosity ( ) const
virtual

Return a reference value typical of the viscosities that appear in this model. This value is not actually used in the material description itself, but is used in scaling variables to the same numerical order of magnitude when solving linear systems. Specifically, the reference viscosity appears in the factor scaling the pressure against the velocity. It is also used in computing dimension-less quantities. You may want to take a look at the Kronbichler, Heister, Bangerth 2012 paper that describes the design of ASPECT for a description of this pressure scaling.

Note
The reference viscosity should take into account the complete constitutive relationship, defined as the scalar viscosity times the constitutive tensor. In most cases, the constitutive tensor will simply be the identity tensor (this is the default case), but this may become important for material models with anisotropic viscosities, if the constitutive tensor is not normalized.

Implements aspect::MaterialModel::Interface< dim >.

§ declare_parameters()

template<int dim>
static void aspect::MaterialModel::Nondimensional< dim >::declare_parameters ( ParameterHandler prm)
static

§ parse_parameters()

template<int dim>
virtual void aspect::MaterialModel::Nondimensional< dim >::parse_parameters ( ParameterHandler prm)
virtual
