Function Documentation

bool_to_string()

const char * bool_to_string ( bool  boolean )

inline

Convert bool to string.

compute_stress() [1/2]

template<unsigned int dim, typename T >

void compute_stress ( const dealii::Tensor< 2, voigt_tensor_size< dim >, T > &  elasticity_tensor, const dealii::Tensor< 1, voigt_tensor_size< dim >, T > &  strain, dealii::Tensor< 1, voigt_tensor_size< dim >, T > &  stress  )

inline

Compute the stress with a given displacement and elasticity tensor. This assumes that the provided parameters are in Voigt notation.

compute_stress() [2/2]

template<unsigned int dim, typename T >

void compute_stress ( const dealii::Tensor< 2, voigt_tensor_size< dim >, T > &  elasticity_tensor, const dealii::Tensor< 2, dim, T > &  strain, dealii::Tensor< 2, dim, T > &  stress  )

inline

Compute the stress with a given displacement and elasticity tensor. Note: this functions internally converts to Voigt notation.

dealii_point_to_vector()

template<unsigned int dim, typename number >

std::vector< number > dealii_point_to_vector ( const dealii::Point< dim, number > &  point )

inline

eval_flags_to_string()

std::string eval_flags_to_string ( dealii::EvaluationFlags::EvaluationFlags  flag )

inline

Convert evaluation flags to string.

pmod()

template<typename Real , typename OtherReal >

Real pmod ( const Real &  value, const OtherReal &  modulus  )

inline

Positive moldulo (remainder) returns the normal remainder. (c++ fmod is defined abnormally for negative numbers)

string_to_type()

template<typename Type >

PRISMS_PF_BEGIN_NAMESPACE Type string_to_type	(	const std::string &	string,
		const std::unordered_map< std::string, Type > &	table
	)

Helper function that converts a string to some type, given a mapping.

string_to_type_pair_with_delimiters()

template<typename Type , typename OtherType >

std::pair< OtherType, Type > string_to_type_pair_with_delimiters	(	const std::string &	string,
		const std::unordered_map< std::string, Type > &	table,
		const std::unordered_map< std::string, OtherType > &	other_table,
		const std::pair< char, char > &	delimiters = {'(', ')'}
	)

Helper function that converts a string to some type pair, given two mappings and a set of delimiters.

Note that this function requires the general form of one of the below cases. Parentheses are used for delimiters for simplicity.

Case 1: Input - Type(OtherType) Output - {OtherType, Type} Case 2: Input - OtherType Output - {OtherType, Type}

The input string would have the types replaced with their respective mappings.

strip_whitespace()

std::string strip_whitespace ( const std::string &  _text )

inline

Remove whitespace from strings.

Variable Documentation

voigt_tensor_size

template<unsigned int dim>

constexpr unsigned int voigt_tensor_size = (2 * dim) - 1 + (dim / 3)

constexpr

Voigt notation index range.
