Detailed Description

template<unsigned int dim, typename number>
class ReadBinary< dim, number >

Class to read in a flat binary file and provide values at given points.

Constructor & Destructor Documentation

ReadBinary()

template<unsigned int dim, typename number>

ReadBinary< dim, number >::ReadBinary ( const InitialConditionFile & _ic_file, const SpatialDiscretization< dim > & _spatial_discretization )

inline

Constructor.

Member Function Documentation

check_file_size()

template<unsigned int dim, typename number>

void ReadBinary< dim, number >::check_file_size ( )

inlineprivate

Check the size of the binary file and make sure it matches the expected size (in bytes).

get_scalar_value()

template<unsigned int dim, typename number>

number ReadBinary< dim, number >::get_scalar_value ( const dealii::Point< dim > & point, const std::string & scalar_name )

inlineoverridevirtual

Get scalar value for a given point.

Implements ReadFieldBase< dim, number >.

get_value()

template<unsigned int dim, typename number>

dealii::Vector< number > ReadBinary< dim, number >::get_value ( const dealii::types::global_dof_index index, const unsigned int n_components )

inlineprivate

Get vector value for a given index.

get_vector_value()

template<unsigned int dim, typename number>

dealii::Vector< number > ReadBinary< dim, number >::get_vector_value ( const dealii::Point< dim > & point, const std::string & vector_name )

inlineoverridevirtual

Get vector value for a given point.

Implements ReadFieldBase< dim, number >.

interpolate()

template<unsigned int dim, typename number>

dealii::Vector< number > ReadBinary< dim, number >::interpolate ( const dealii::Point< dim > & point, const unsigned int n_components )

inlineprivate

Get vector value for a given point.

This function is necessary for binary files because we don't have a strict order of points that deal.II gives us in the initial condition function. For that reason, we have to interpolate the flat binary values assuming a rectangular grid with fixed spacing. Furthermore, we assume that the first point is the origin (0,0,0) and the last the furthest corner (increasing x, then y, and z).

print_file()

template<unsigned int dim, typename number>

void ReadBinary< dim, number >::print_file ( )

inlineoverridevirtual

Print the binary file to text for debugging.

Implements ReadFieldBase< dim, number >.

write_file()

template<unsigned int dim, typename number>

void ReadBinary< dim, number >::write_file ( const std::vector< number > & data, const InitialConditionFile & ic_file )

inlinestatic

Write a binary file for testing.

Member Data Documentation

data

template<unsigned int dim, typename number>

std::vector<number> ReadBinary< dim, number >::data

private

Data array to hold the read in values.

n_points

template<unsigned int dim, typename number>

dealii::types::global_dof_index ReadBinary< dim, number >::n_points = 1

private

Number of grid points.

We have to set the initial value to 1 so that when we multiply in the constructor we don't end up with zero.

n_values

template<unsigned int dim, typename number>

dealii::types::global_dof_index ReadBinary< dim, number >::n_values = 0

private

Number of values (n_points * n_components).
