smash::ThermodynamicLatticeOutput Class Reference

#include <thermodynamiclatticeoutput.h>

Writes the thermodynamic quantities at lattice points versus time.

This class is a temporary solution to write thermodynamic quantities out. Calculations are called directly inside the output functions. In future it should be substituted by some more general output.

at_eventstart() [1/2]

void smash::ThermodynamicLatticeOutput::at_eventstart ( const int  event_number, const ThermodynamicQuantity  tq, const DensityType  dens_type, const RectangularLattice< DensityOnLattice >  lattice  )

overridevirtual

Output launched at event start after initialization, when particles are generated but not yet propagated.

Parameters

[in]	event_number	Number of the current event.
[in]	tq	Thermodynamic quantity to deal with
[in]	dens_type	Density type for the reference frame.
[in]	lattice	Specialized Lattice for DensityOnLattice

Note

This method takes the event number and not the ensemble number as the lattice is meant to contain an average over ensembles if multiple ensembles are used.
