Functions
double	smash::calc_hubble (double time, const ExpansionProperties &metric)
	Calculate the Hubble parameter \(H(t)\), which describes how large the expansion flow is. More...
double	smash::propagate_straight_line (Particles *particles, double to_time, const std::vector< FourVector > &beam_momentum)
	Propagates the positions of all particles on a straight line to a given moment. More...
void	smash::expand_space_time (Particles *particles, const ExperimentParameters &parameters, const ExpansionProperties &metric)
	Modifies positions and momentum of all particles to account for space-time deformation. More...
void	smash::update_momenta (Particles *particles, double dt, const Potentials &pot, RectangularLattice< std::pair< ThreeVector, ThreeVector >> *FB_lat, RectangularLattice< std::pair< ThreeVector, ThreeVector >> *FI3_lat)
	Updates the momenta of all particles at the current time step according to the equations of motion: More...
