template<class Init, class Coefficients>
walker::Position class

Position equation used polymorphically with DiffEq.

Contents

The template arguments specify policies and are used to configure the behavior of the class. The policies are:

  • Init - initialization policy, see DiffEq/InitPolicy.h
  • Coefficients - coefficients policy, see DiffEq/PositionCoeffPolicy.h

Constructors, destructors, conversion operators

Position(ncomp_t c) explicit
Constructor.

Public functions

void initialize(int stream, tk::Particles& particles)
void advance(tk::Particles& particles, int, tk::real dt, tk::real, const std::map<tk::ctr::Product, tk::real>&)
Advance particles according to the system of position SDEs.

Function documentation

template<class Init, class Coefficients>
walker::Position<Init, Coefficients>::Position(ncomp_t c) explicit

Constructor.

Parameters
c in Index specifying which system of position SDEs to construct There can be multiple position ... end blocks in a control file. This index specifies which position SDE system to instantiate. The index corresponds to the order in which the position ... end blocks are given the control file.

template<class Init, class Coefficients>
void walker::Position<Init, Coefficients>::initialize(int stream, tk::Particles& particles)

Parameters
stream in Thread (or more precisely stream) ID
particles in/out Array of particle properties

Initalize SDE, prepare for time integration

Set initial conditions using initialization policy

template<class Init, class Coefficients>
void walker::Position<Init, Coefficients>::advance(tk::Particles& particles, int, tk::real dt, tk::real, const std::map<tk::ctr::Product, tk::real>&)

Advance particles according to the system of position SDEs.

Parameters
particles in/out Array of particle properties
dt in Time step size
