List of all members.

Public Member Functions
	StartHomogen ()
	Default constructor.
virtual	~StartHomogen ()
	Destructor.
void	Init ()
	Initialize Generation and unnormalize the density.
bool	Execute ()
	Distributes particles evenly throughout the grid. Calculate the number of superparticles per cell from the area of a grid cell and and the superparticle size. Then iterate through the grid and distribute the particles evenly using the VelocityGeneration function.
Public Member Functions inherited from Generation
	Generation ()
	Default constructor.
virtual	~Generation ()
	Destructor.
std::string	GetClassName () const
	Returns the name of the class, here "generation".
Public Member Functions inherited from Task
	Task ()
	Default constructor sets the running number nNr of the Task.
virtual	~Task ()
	When destructing a Task is has to be detatched from the parents Task list.
int	GetStep () const
	Return the interval between execution in timesteps.
int	GetEnd () const
	Return the timestep when the Task ends execution.
bool	DoNow ()
	Returns true if the Task is to be executed now.
std::string	GetName () const
	Returns the name given to the Task object.
virtual bool	IsInteractive () const
	If not specified otherwise, a Task is not interactive.
void	AttachTask (Task *pTask)
	Insert Task into Task list and registers it with the Process.
void	DetachTask (Task *pTask)
	DetachTask from Task list.
virtual std::string	Rebuild (std::istream &in)
	Rebuilds the task from the setup. This normally does not need to be overwritten. Rebuild always returns the next token that does not belong to the object setup.
virtual void	DumpTaskList (std::ostream &o, int nDepth=0)
	Recursively dumps the complete Task list into a stream.

Protected Member Functions
PARAMETERMAP *	MakeParamMap (PARAMETERMAP *pm=NULL)
	Register the parameters needed for the Task. A derived class should overwrite this whenever it needs additional parameters from the setup file. It should then ALWAYS call the MakeParamMap of its superclass.
double	VelocityGeneration (double v)
	Generate a velocity component according to Maxwell distribution.
void	InputVeloDistribution (Velocity V, double cs, double Vn)
	Determination of the velocity distribution of the super particles. 2000 interval steps are used.
void	OutputVeloDistribution ()
	Output of the velocity distribution of the super particles. 2000 interval steps (resolution of the distribution function) are used.
