Detailed Description

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

An incompressible material model which is intended for use with multiple compositional fields. Each compositional field is meant to be a single rock type, where the value of the field at a point is interpreted to be a volume fraction of that rock type. If the sum of the compositional field volume fractions is less than one, then the remainder of the volume is assumed to be ``background mantle''. If the sum of the compositional field volume fractions is greater than one, then they are renormalized to sum to one and there is no background mantle.

For each material parameter the user supplies a comma delimited list of length N+1, where N is the number of compositional fields. The additional field corresponds to the value for background mantle. They should be ordered ``background, composition1, composition2...''

If a single value is given, then all the compositional fields are given that value. Other lengths of lists are not allowed. For a given compositional field the material parameters are treated as constant, except density, which varies linearly with temperature according to the thermal expansivity.

When more than one field is present at a point, they are averaged arithmetically. An exception is viscosity, which may be averaged arithmetically, harmonically, geometrically, or by selecting the viscosity of the composition with the greatest volume fraction.

Member Function Documentation

§ evaluate()

template<int dim>

void aspect::MaterialModel::Multicomponent< dim >::evaluate	(	const MaterialModel::MaterialModelInputs< dim > &	in,
		MaterialModel::MaterialModelOutputs< dim > &	out
	)		const

overridevirtual

Function to compute the material properties in out given the inputs in in. If MaterialModelInputs.strain_rate has the length 0, then the viscosity does not need to be computed.

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

§ is_compressible()

template<int dim>

bool aspect::MaterialModel::Multicomponent< dim >::is_compressible ( ) const

overridevirtual

This model is not compressible, so this returns false.

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

§ reference_viscosity()

template<int dim>

double aspect::MaterialModel::Multicomponent< dim >::reference_viscosity ( ) const

overridevirtual

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::Multicomponent< dim >::declare_parameters ( ParameterHandler & prm )

static

Declare the parameters this class takes through input files.

§ parse_parameters()

template<int dim>

void aspect::MaterialModel::Multicomponent< dim >::parse_parameters ( ParameterHandler & prm )

overridevirtual

Read the parameters this class declares from the parameter file.

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