Detailed Description

Functions for creating the environment and launching the simulation.

This section describes the functions for initialising SURF, performing the simulation and exiting SURF.

Function Documentation

void surf_init ( int *  argc,
char **  argv 
)

Initialize SURF.

Parameters
argcargument number
argvarguments

This function has to be called to initialize the common structures. Then you will have to create the environment by calling e.g. surf_workstation_model_init_CLM03()

See Also
surf_workstation_model_init_CLM03(), surf_workstation_model_init_compound(), surf_exit()
void surf_presolve ( void  )

Finish simulation initialization.

This function must be called before the first call to surf_solve()

double surf_solve ( double  max_date)

Performs a part of the simulation.

Parameters
max_dateMaximum date to update the simulation to, or -1
Returns
the elapsed time, or -1.0 if no event could be executed

This function execute all possible events, update the action states and returns the time elapsed. When you call execute or communicate on a model, the corresponding actions are not executed immediately but only when you call surf_solve. Note that the returned elapsed time can be zero.

double surf_get_clock ( void  )

Return the current time.

Return the current time in millisecond.

void surf_exit ( void  )

Exit SURF.

Clean everything.
