Detailed Description

A class representing a fragment in a discrete element method simulation.

This class contains properties and methods for defining and manipulating DEM fragments, which can be used to model particles in simulations of granular materials and other systems.

Member Function Documentation

InitLevelSet()

void DEMFragment::InitLevelSet	(	double	corner_x,
		double	corner_y,
		double	corner_z,
		double	sp,
		int	dim_x,
		int	dim_y,
		int	dim_z )

Initializes the level set function for this fragment.

The level set function is used to represent the interface between the fragment and its surrounding medium.

Parameters

corner_x	The x coordinate of the corner of the bounding box for the level set function.
corner_y	The y coordinate of the corner of the bounding box for the level set function.
corner_z	The z coordinate of the corner of the bounding box for the level set function.
sp	The spacing between grid points in the level set function.
dim_x	The number of grid points along the x axis of the level set function.
dim_y	The number of grid points along the y axis of the level set function.
dim_z	The number of grid points along the z axis of the level set function.

ReInitSTLModel()

void DEMFragment::ReInitSTLModel

(

)

Reinitializes the STL model for this fragment.

This method reloads the STL file associated with this fragment and updates its vertices and normals.

ResolverOverlap()

void DEMFragment::ResolverOverlap

(

DEMFragment *const

frag_q

)

Resolves any overlaps between this fragment and another fragment.

If there is an overlap between this fragment and the given fragment frag_q, this method adjusts the positions of both fragments so that they no longer overlap.

Parameters

frag_q

A pointer to another DEMFragment object.
