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

Dirichlet SDE 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/DirCoeffPolicy.h

Constructors, destructors, conversion operators

Dirichlet(ncomp_t c) explicit
Constructor.

Public functions

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

Function documentation

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

Constructor.

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

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

Advance particles according to the Dirichlet SDE.

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