template<class Init, class Coefficients>
Velocity class
Velocity 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/VelocityCoeffPolicy.h
Constructors, destructors, conversion operators

-
void advance(tk::Particles& particles,

tk::
real dt, tk:: real t, const std::map<tk:: ctr:: Product, tk:: real>& moments) - Advance particles according to the system of velocity SDEs.
Function documentation
template<class Init, class Coefficients>
walker:: Velocity<Init, Coefficients>:: Velocity(ncomp_ t c) explicit
Constructor.
Parameters | |
---|---|
c in | Index specifying which system of velocity SDEs to construct There can be multiple velocity ... end blocks in a control file. This index specifies which velocity SDE system to instantiate. The index corresponds to the order in which the velocity ... end blocks are given the control file. |
template<class Init, class Coefficients>
std::size_t walker:: Velocity<Init, Coefficients>:: numderived() const
Returns | Number of derived variables computed |
---|
Compute number of derived variables

Parameters | |
---|---|
stream in | Thread (or more precisely stream) ID |
particles in/out | Array of particle properties |
Initalize SDE, prepare for time integration
