Atom Class Reference

An atom has an unique index in the physical model object, a 3D position, and different basic properties. It is the most basic structure composing a physical model. It is on an atoms that the forces and loads could be applied in order to generate dynamics. More...

Detailed Description

An atom has an unique index in the physical model object, a 3D position, and different basic properties. It is the most basic structure composing a physical model. It is on an atoms that the forces and loads could be applied in order to generate dynamics.

Constructor & Destructor Documentation

Atom() [1/5]

Atom::Atom

(

PhysicalModel *

myPM

)

Default constructor : set the position to the origin, generate a unique index.

Parameters

myPM	the physical model the atom belongs to

References Structure::properties.

Atom() [2/5]

Atom::Atom	(	PhysicalModel *	myPM,
		physicalModel::Atom	atom,
		unsigned int	id = -1
	)

constructor from xml node: try to read and get the parameters from xml and set the index in atom SC (if possible)

Parameters

myPM	the physical model the atom belongs to
atom	the xsd class representing the atom to read information from.
id	the index in the atoms structural component (useful to directly access the memory block corresponding to the position)
