Detailed Description

Contains the main rotutines for LGRID.

Enumeration Type Documentation

limiter_type

enum limiter_type

Keyword token types.

• degrees Limiter defined in degrees.
• radians Limiter defined in radians.
• eof End of file reached.

Function Documentation

get_next_keyword()

const limiter_type get_next_keyword

(

std::ifstream &

file

)

Finds the next keyword.

Reads the input file one file at a time searching for the next keyword until the end of the file is reached.

Parameters

[in,out]

file

Input file stream to seach for next keyword.

Returns

An limiter_type token.

main()

int main	(	int	argc,
		const char *	argv[]
	)

Main program.

Parses the limter file. Computes distances to the nearest limiter element. Creates the lgrid netcdf file. This program expects 7 arguments in the following order.

• Filename to parse define the limiter.
• Starting radial position to define the radial grid.
• Radial grid spacing.
• Number of radial grid points.
• Starting vertical position to define the vertical grid.
• Vertical grid spacing.
• Number of vertical grid points.

Parameters

[in]	argc	Number of command line arguments.
[in]	argv	Arrays of argument strings.

Returns

0 if completed.

parse_limiter()

void parse_limiter	(	std::ifstream &	file,
		std::map< const double, std::vector< vertex * > > &	limiters,
		const limiter_type	type
	)

Parses a limiter specification.

Limiters are defined by the number of phi planes this plasma facing component is asscoiated with. This is followed by a list of each phi. A collection of R, Z values defing the crossection is read until two doubles could not be read or the file ends.

Parameters

[in,out]	file	Input file stream read limiter from.
[in,out]	limiters	Limiter vertex data.
[in]	type	Limiter type.

parse_limiter_file()

std::map<const double, std::vector<vertex *> > parse_limiter_file

(

const std::string &

file_name

)

Parses a limiter specification.

Opens a file, loops through all the keywords and parses the limiter file.

Parameters

[in]

file_name

Limiter type.

Returns

An limiter_type token.

Variable Documentation

new_limiter_deg

const std::string new_limiter_deg = "new_limiter_deg"

Limiter plane keyword specified in degrees.

LGRID is code for generating responce files for any arbitary shaped limiter structure. This creates a grid a distances to the nearest plasma facing component in a specified phi plane.
