LevelSetSplittor

C++: phynexis::peridigm::LevelSetSplittor
Python: phynexis.peridigm.LevelSetSplittor
Header: src/peridigm/level_set_splittor.hpp

Description

Domain splitter that uses a level set (signed distance) function to define the geometry. Supports initialization from STL models or distance map files.

Inherits from DomainSplittor and LevelSetField.

Constructors

LevelSetSplittor()

Creates an empty level set splitter.

Example:

import phynexis
splittor = phynexis.peridigm.LevelSetSplittor()
print(type(splittor))

Output:

<class 'phynexis.lib.pyperidigm.LevelSetSplittor'>

Methods

init_from_stl(stl_model, num_ele_each)

Initializes the splitter from an STLModel object, creating an internal level set representation.

Parameters:

Parameter	Type	Description
stl_model	STLModel	STL model object
num_ele_each	int	Number of elements in each dimension

init_from_distance_map(file_name)

Initializes from a distance map text file.

Parameters:

Parameter	Type	Description
file_name	str	Path to the distance map file

init_from_distance_map(corner_x, corner_y, corner_z, sp, dim_x, dim_y, dim_z, dist_list)

Initializes from an explicit list of distances on a regular grid.

Parameters:

Parameter	Type	Description
corner_x	float	X coordinate of grid corner
corner_y	float	Y coordinate of grid corner
corner_z	float	Z coordinate of grid corner
sp	float	Grid spacing
dim_x	int	Number of grid points along x
dim_y	int	Number of grid points along y
dim_z	int	Number of grid points along z
dist_list	list[float]	Distance values (flattened grid)
