Detailed Description

template<typename P>
class Physics::TracerParticle::TracerParticleStepper

Implementation of TimeStepper for advancing tracer particles in a fixed velocity field.

The template requirements on the particle type P are the same as for TracerParticleSolver with the addition of templated functions of the type RealVect& P::vector<size_t>() which returns a RealVect. This is used for the Runge-Kutta particle advection kernels. This class will work fine with TracerParticle<0, M> where M >= 4.
