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 54 of file FibreReader.hpp.

Constructor & Destructor Documentation

template<unsigned DIM>

FibreReader< DIM >::FibreReader	(	FileFinder &	rFileFinder,
		FibreFileType	fibreFileType
	)			`[inline]`

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 35 of file FibreReader.cpp.

Member Function Documentation

template<unsigned DIM>

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

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 66 of file FibreReader.cpp.

References EXCEPTION, FibreReader< DIM >::GetNextFibreVector(), FibreReader< DIM >::mNumItemsPerLine, and FibreReader< DIM >::mNumLinesOfData.

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
	)			`[inline]`

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)

template<unsigned DIM>

void FibreReader< DIM >::GetNextFibreSheetAndNormalMatrix	(	c_matrix< double, DIM, DIM > &	rFibreMatrix,
		bool	checkOrthogonality = `true`
	)			`[inline]`

Read the next 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:

	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 >::GetNextFibreVector	(	c_vector< double, DIM > &	rFibreVector,
		bool	checkNormalised = `true`
	)			`[inline]`

Read the next 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:

	rFibreVector	vector to be filled in
	checkNormalised	if true, checks if the read vector is normalised and throws an exception if not

unsigned FibreReader< DIM >::GetNumLinesOfData ( ) [inline]

Get the number of lines of data in the file - this is the value read from the first line.

unsigned FibreReader< DIM >::GetTokensAtNextLine ( ) [inline, private]

Read a line of numbers from mDataFile. Sets up the member variable mTokens with the data in the next line.

Returns:: the number of data entries put into mTokens
