dVector6

dVector6 is a static storage container which stores a vector of six double values. It is used to store mechanical stress and strain loads in Voigt notations, as a storage unit in Storage3D container.

The data inside of the dVector6 container is manipulated using a number of dedicated methods:

Constructors

cpp
dVector6();
Default constructor, sets vector values to zero;

cpp
dVector6(const dVector6& vecinit);
Copy constructor, initializes the current vector with a copy of vecinit.

cpp
dVector6(std::array<double,6> vecinit);
Constructor, initializes the current vector with a copy of vecinit.

cpp
dVector6(std::initializer_list<double> vecinit);
Constructor, initializes the current vector using initializer list vecinit.

Access operators

cpp

double& operator[](const size_t i);
double const& operator[](const size_t i) const;

Return (const) reference to the element i.

cpp
double* data(void);
const double* data(void) const;
Returns (const) pointer to the first element of the vector.

Arithmetic and vector operations

cpp
dVector6 operator*(const double m) const;
Returns current vector with all components multiplied by the factor m.

cpp
dVector6 operator/(const double m) const;
Returns current vector with all components divided by the factor m.

cpp
dVector6 operator+(const dVector6& rhs) const;
Returns the sum of two vectors.

cpp
dVector6 operator-(const dVector6& rhs) const;
Returns the difference of two vectors.

cpp
dVector6& operator*=(const double m);
Multiplies all entries of the current vector by the factor m.

cpp
dVector6& operator/=(const double m);
Divides all entries of the current vector by the factor m.

cpp
dVector6& operator-=(const dVector6& rhs);
Subtracts vector rhs from the current vector.

cpp
dVector6& operator+=(const dVector6& rhs);
Adds vector rhs to the current vector.

cpp
dVector6& operator=(const dVector6& rhs);
Assigns the content of the vector rhs to the current vector.

cpp
double max_abs(void) const;
Returns maximum element of the current vector.

cpp
double norm(double p);
Returns Frobenius norm of the current vector.

Data manipulation methods

cpp
void set_to_zero(void);
Sets all entries to zero.

cpp
void set_to_unity(void);
Sets all entries to one.

Container properties

cpp
constexpr size_t size(void) const;
Returns the size of the stored vector.

MPI communication methods

cpp
void pack(std::vector<double>& buffer);
The method, which packs the content of the current object into the MPI communication buffer.

cpp
void unpack(std::vector<double>& buffer, size_t& it);
The method, which unpacks (reads) the content of the current dVector3 object from the MPI communication buffer. The existing data in the container is overwritten.

Read/write methods

cpp
std::string print(void) const;
Returns formatted string of the vector values ready to print to the terminal.

cpp
void read_ASCII(std::istream& inp);
Reads vector content from the input stream.

cpp
void write_ASCII(std::ostream& outp, const int precision = 16, const char sep = ' ') const;
Writes vector content in ASCII format with the specified precision using sep as entry separator into the output stream.

cpp
std::string get_output_string(const int precision = 16, const char sep = ' ') const;
Returns output string with vector content in ASCII format with the specified precision using sep as entry separator.

cpp
std::vector<double> get_vector() const;
Returns std::vector containing current vector components.

cpp
std::vector<float> get_vector_float() const;
Returns std::vector<float> containing current vector components rounded to float precision.
