Detailed Description

template<unsigned DIM>
class FibreReader< DIM >

A class for reading .axi files (files which define the fibre direction for each element) and .ortho files (files which define the fibre, sheet and normal directions for each element.

Definition at line 61 of file FibreReader.hpp.

Constructor & Destructor Documentation

template<unsigned DIM>

FibreReader< DIM >::FibreReader	(	const FileFinder &	rFileFinder,
		FibreFileType	fibreFileType
	)

Create a new FibreReader.

Parameters

rFileFinder	the path to the fibre direction file
fibreFileType	AXISYM or ORTHO depending on type of file to be read

Definition at line 42 of file FibreReader.cpp.

Member Function Documentation

template<unsigned DIM>

void FibreReader< DIM >::GetAllAxi ( std::vector< c_vector< double, DIM > > & direction )

Get every line of a fibre file (axi-symmetric) in vector of vectors format. This is useful for adding to a visualizer. (Do not use with GetNext...)

Parameters

direction an empty vector which will be filled with data from file

Definition at line 74 of file FibreReader.cpp.

template<unsigned DIM>

void FibreReader< DIM >::GetAllOrtho	(	std::vector< c_vector< double, DIM > > &	first_direction,
		std::vector< c_vector< double, DIM > > &	second_direction,
		std::vector< c_vector< double, DIM > > &	third_direction
	)

Get every line of a fibre file (orthotropic) in vector of vectors format. This is useful for adding to a visualizer. (Do not use with GetNext...)

Parameters

first_direction	an empty vector which will be filled with data from file
second_direction	an empty vector which will be filled with data from file
third_direction	an empty vector which will be filled with data from file (or will remain empty in 2D)

void FibreReader< DIM >::GetFibreSheetAndNormalMatrix	(	unsigned	fibreIndex,
		c_matrix< double, DIM, DIM > &	rFibreMatrix,
		bool	checkOrthogonality = `true`
	)

Read a fibre direction matrix from the file. Must only be used when reading an orthotropic file. These have lines of the form

fibre0 fibre1 fibre2 sheet0 sheet1 sheet2 normal0 normal1 normal2

which are converted to the matrix

[ fibre0   sheet0   normal0  ]
[ fibre1   sheet1   normal1  ]
[ fibre2   sheet2   normal2  ]

Parameters

fibreIndex	which fibre vector to read. Note that vectors must be read in monotonically increasing order, so subsequent calls to this method must always pass a strictly greater index. They may skip vectors, however.
rFibreMatrix	matrix to be filled in
checkOrthogonality	if true, checks if the matrix is orthogonal and throws an exception if not

template<unsigned DIM>

void FibreReader< DIM >::GetFibreVector	(	unsigned	fibreIndex,
		c_vector< double, DIM > &	rFibreVector,
		bool	checkNormalised = `true`
	)

Read a fibre direction vector from the file. Must only be used when reading an axisymmetric file. These have lines of the form

fibre0 fibre1 fibre2

Parameters

fibreIndex	which fibre vector to read. Note that vectors must be read in monotonically increasing order, so subsequent calls to this method must always pass a strictly greater index. They may skip vectors, however.
rFibreVector	vector to be filled in
checkNormalised	if true, checks if the read vector is normalised and throws an exception if not
