◆ SnowpackInterface() [1/2]

SnowpackInterface::SnowpackInterface	(	const mio::Config &	io_cfg,
		const size_t &	nbworkers,
		const mio::DEMObject &	dem_in,
		const mio::Grid2DObject &	landuse_in,
		const std::vector< mio::Coords > &	vec_pts,
		const mio::Date &	startTime,
		const std::string &	grids_requirements,
		const bool	is_restart_in
	)

Constructs and initialise Snowpack Interface Master. He creates the Worker and Distributes the Data from the other modules to the Worker. Is the acces interface A3D side.

Parameters

io_cfg	is used to create IOManager, which is used to write the standart output
nbworkers	gives the new values for the wind speed
dem_in	gives the demographic Data. Also tetermines size and position of the geographical modeling scope
landuse_in	gives the landuse Data. Also tetermines size and position of the landuse for modeling scope
vec_pts	gives the spezial points. For this points more output is done then for the others. Calcualtion is the same.
startTime	is the time and date the first simulation step is done
grids_requirements	list of grids that must be prepared for other modules (similar to the Output::GRIDS_PARAMETERS configuration key)
is_restart_in	is used to know which files the worker needs to read to init the pixel

Parameters

date	is the date for which the output is done

◆ writeOutputSNO()

void SnowpackInterface::writeOutputSNO ( const mio::Date & date )

commands worker to write .sno files. Is triggered by Alpine Control

Hack --> Find better software architecture to do this then SnowpackInterface also does output for other modules of A3D here..

Parameters

date	is the date witch the output is done
