Detailed Description

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

A material model that relies on compositional fields that stand for average grain sizes of a mineral phase and source terms for them that determine the grain size evolution in dependence of the strain rate, temperature, phase transitions, and the creep regime. This material model only works if a compositional field named 'grain_size' is present. In the diffusion creep regime, the viscosity depends on this grain size. We use the grain size evolution laws described in Behn et al., 2009. Implications of grain size evolution on the seismic structure of the oceanic upper mantle, Earth Planet. Sci. Letters, 282, 178–189. Other material parameters are either prescribed similar to the 'simple' material model, or read from data files that were generated by the Perplex or Hefesto software. The material model is described in more detail in Dannberg, J., Z. Eilon, U. Faul, R. Gassmöller, P. Moulik, and R. Myhill (2017), The importance of grain size to mantle dynamics and seismological observations, Geochem. Geophys. Geosyst., 18, 3034–3061, doi:10.1002/2017GC006944., which is the canonical reference for this material model.

Member Function Documentation

§ initialize()

template<int dim>
void aspect::MaterialModel::GrainSize< dim >::initialize ( )
overridevirtual

Initialization function. Loads the material data and sets up pointers.

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

§ is_compressible()

template<int dim>
bool aspect::MaterialModel::GrainSize< dim >::is_compressible ( ) const
overridevirtual

Return whether the model is compressible or not. Incompressibility does not necessarily imply that the density is constant; rather, it may still depend on temperature or pressure. In the current context, compressibility means whether we should solve the continuity equation as \(\nabla \cdot (\rho \mathbf u)=0\) (compressible Stokes) or as \(\nabla \cdot \mathbf{u}=0\) (incompressible Stokes).

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

§ evaluate()

template<int dim>
void aspect::MaterialModel::GrainSize< dim >::evaluate ( const typename Interface< dim >::MaterialModelInputs in,
typename Interface< dim >::MaterialModelOutputs out 
) const
override

§ declare_parameters()

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

Declare the parameters this class takes through input files.

§ parse_parameters()

template<int dim>
void aspect::MaterialModel::GrainSize< dim >::parse_parameters ( ParameterHandler &  prm)
overridevirtual

Read the parameters this class declares from the parameter file.

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

§ create_additional_named_outputs()

template<int dim>
void aspect::MaterialModel::GrainSize< dim >::create_additional_named_outputs ( MaterialModel::MaterialModelOutputs< dim > &  outputs) const
overridevirtual

If this material model can produce additional named outputs that are derived from NamedAdditionalOutputs, create them in here. By default, this does nothing.

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

§ enthalpy()

template<int dim>
double aspect::MaterialModel::GrainSize< dim >::enthalpy ( const double  temperature,
const double  pressure,
const std::vector< double > &  compositional_fields,
const Point< dim > &  position 
) const

Returns the enthalpy as calculated by HeFESTo.

§ enthalpy_derivative()

template<int dim>
std::array<std::pair<double, unsigned int>,2> aspect::MaterialModel::GrainSize< dim >::enthalpy_derivative ( const typename Interface< dim >::MaterialModelInputs in) const

Returns the cell-wise averaged enthalpy derivatives for the evaluate function and postprocessors. The function returns two pairs, the first one represents the temperature derivative, the second one the pressure derivative. The first member of each pair is the derivative, the second one the number of vertex combinations the function could use to compute the derivative. The second member is useful to handle the case no suitable combination of vertices could be found (e.g. if the temperature and pressure on all vertices of the current cell is identical.

§ viscosity()

template<int dim>
double aspect::MaterialModel::GrainSize< dim >::viscosity ( const double  temperature,

§ dislocation_viscosity()

template<int dim>
double aspect::MaterialModel::GrainSize< dim >::dislocation_viscosity ( const double  temperature,
const double  pressure,
const std::vector< double > &  compositional_fields,
const SymmetricTensor< 2, dim > &  strain_rate,
const Point< dim > &  position,
const double  viscosity_guess = 0 
) const
protected

This function calculates the dislocation viscosity. For this purpose we need the dislocation component of the strain rate, which we can only compute by knowing the dislocation viscosity. Therefore, we iteratively solve for the dislocation viscosity and update the dislocation strain rate in each iteration using the new value obtained for the dislocation viscosity. The iteration is started with a dislocation viscosity calculated for the whole strain rate unless a guess for the viscosity is provided, which can reduce the number of iterations significantly.

§ dislocation_viscosity_fixed_strain_rate()

template<int dim>
double aspect::MaterialModel::GrainSize< dim >::dislocation_viscosity_fixed_strain_rate ( const double  temperature,
const double  pressure,
const std::vector< double > &  ,

Rate of grain size growth (Ostwald ripening) or reduction (due to dynamic recrystallization and phase transformations) in dependence on temperature, pressure, strain rate, mineral phase and creep regime. We use the grain size growth laws as for example described in Behn, M. D., Hirth, G., & Elsenbeck, J. R. (2009). Implications of grain size evolution on the seismic structure of the oceanic upper mantle. Earth and Planetary Science Letters, 282(1), 178-189.

For the rate of grain size reduction due to dynamic crystallization there is the choice between the paleowattmeter (Austins and Evans, 2007) and the paleopiezometer (Hall and Parmentier, 2003) as described in the parameter use_paleowattmeter.

§ phase_function()

template<int dim>
double aspect::MaterialModel::GrainSize< dim >::phase_function ( const Point< dim > &  position,
const double  temperature,
const double  pressure,
const unsigned int  phase

void aspect::MaterialModel::GrainSize< dim >::convert_log_grain_size ( std::vector< double > &  compositional_fields) const
protected

Function that takes an object in the same format as in.composition as argument and converts the vector that corresponds to the grain size to its logarithms and limits the grain size to a global minimum. The input argument compositional_fields is modified in-place.
