Constructor & Destructor Documentation

PeriDigmDiscretization()

PeriDigmDiscretization::PeriDigmDiscretization

(

)

Default constructor.

~PeriDigmDiscretization()

PeriDigmDiscretization::~PeriDigmDiscretization

)

Destructor.

Member Function Documentation

GetNodeSize()

double PeriDigmDiscretization::GetNodeSize

(

)

Gets the average size of the nodes in the discretization.

This method gets the average size of the nodes in the discretization by computing the average distance between adjacent nodes.

Returns

The average size of the nodes.

InitFromDistanceMap()

void PeriDigmDiscretization::InitFromDistanceMap

(

std::string const &

txt_file

)

Initializes the discretization from a distance map.

This method initializes the discretization from a distance map text file by using the values as level set distances and dividing the resulting volume into elements of equal size.

Parameters

txt_file

The path to the distance map text file.

InitFromGrid()

void PeriDigmDiscretization::InitFromGrid	(	double	corner_x,
		double	corner_y,
		double	corner_z,
		double	len_x,
		double	len_y,
		double	len_z,
		int	num_ele_each )

Initializes the discretization from a regular grid.

This method initializes the discretization from a regular grid by dividing the volume into elements of equal size. The origin of the grid is the corner with the minimum (x,y,z) coordinates.

Parameters

corner_x	The x-coordinate of the corner of the grid.
corner_y	The y-coordinate of the corner of the grid.
corner_z	The z-coordinate of the corner of the grid.
len_x	The length of the grid in the x-direction.
len_y	The length of the grid in the y-direction.
len_z	The length of the grid in the z-direction.
num_ele_each	The number of elements in each dimension.

InitFromSTL() [1/2]

void netdem::PeriDigmDiscretization::InitFromSTL	(	std::string const &	stl_file,
		int	num_ele_each )

Initializes the discretization from an STL file.

This method initializes the discretization from an STL file by creating a level set representation of the surface and dividing it into elements of the specified size.

Parameters

stl_file	The path to the STL file.
num_ele_each	The number of elements in each dimension.

InitFromSTL() [2/2]

void PeriDigmDiscretization::InitFromSTL	(	STLModel const &	stl_model,
		int	num_ele_each )

Initializes the discretization from an STL model.

This method initializes the discretization from an STL model by creating a level set representation of the surface and dividing it into elements of the specified size.

Parameters

stl_model	The STLModel object representing the surface.
num_ele_each	The number of elements in each dimension.

MakePorosity()

void PeriDigmDiscretization::MakePorosity

(

double

porosity

)

Modifies the node volumes to achieve a specified porosity.

This method modifies the node volumes to achieve a specified porosity by scaling all volumes by the same factor such that the overall volume is reduced by the given porosity fraction.

Parameters

porosity

The desired porosity.

WriteNodeFile()

void PeriDigmDiscretization::WriteNodeFile

(

std::string const &

result_dir

)

Writes the node information to file.

This method writes the node information (positions, block indices, volumes) to file in the specified directory.

Parameters

result_dir

The path to the directory where the node file should be written.
