Detailed Description

Particle point class for 3D.

A collection of particle coordinates (t,x,vx,y,vy,z,vz)to describe time, location and velocity in 3D.

Constructor & Destructor Documentation

ParticleP3D::ParticleP3D ( ) [inline]

Default constuctor.

ParticleP3D::ParticleP3D	(	double	t,
		double	x,
		double	vx,
		double	y,
		double	vy,
		double	z,
		double	vz
	)			`[inline]`

Constructor for 3D particle point.

ParticleP3D::ParticleP3D ( std::istream & s ) [inline]

Member Function Documentation

static size_t ParticleP3D::dim ( void ) [inline, static]

Returns number of dimensions for geometry.

static geom_mode_e ParticleP3D::geom_mode ( void ) [inline, static]

Returns geometry mode.

static int ParticleP3D::get_derivatives	(	double	t,
		const double *	x,
		double *	dxdt,
		void *	data
	)			`[static]`

Returns time derivatives dxdt of coordinates at time t and coordinates x = (x,vx,y,vy,z,vz) for one particle.

The calculation of particle trajectory is done by integrating the Lorentz equation in a form of a set of ordinary differential equations. In the case of 3D the set is:

$\begin{eqnarray*} \frac{dx}{dt} &=& v_x \\ \frac{dy}{dt} &=& v_y \\ \frac{dz}{dt} &=& v_z \\ \frac{dv_x}{dt} &=& a_x = \frac{q}{m}(E_x + v_y B_z - v_z B_y) \\ \frac{dv_y}{dt} &=& a_y = \frac{q}{m}(E_y + v_z B_x - v_x B_z) \\ \frac{dv_z}{dt} &=& a_z = \frac{q}{m}(E_z + v_x B_y - v_y B_x) \end{eqnarray*}$
