Detailed Description

Particle point class for 2D.

A collection of particle coordinates (t,x,vx,y,vy) to describe time, location and velocity in 2D.

Constructor & Destructor Documentation

ParticleP2D::ParticleP2D ( )
inline

Default constuctor.

ParticleP2D::ParticleP2D ( double  t,
double  x,
double  vx,
double  y,

Member Function Documentation

static size_t ParticleP2D::dim ( void  )
inlinestatic

Returns number of dimensions for geometry.

static geom_mode_e ParticleP2D::geom_mode ( void  )
inlinestatic

Returns geometry mode.

static int ParticleP2D::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) 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 2D the set is:

\begin{eqnarray*} \frac{dx}{dt} &=& v_x \\ \frac{dy}{dt} &=& v_y \\ \frac{dv_x}{dt} &=& a_x = \frac{q}{m}(E_x + v_y B_z) \\ \frac{dv_y}{dt} &=& a_y = \frac{q}{m}(E_y - v_x B_z) \end{eqnarray*}
