Input File

The input file to LEDG specifies the size of the lattice, and the classification of cells. Its syntax is as follows:

LEDG_input_file  ::

	header { body_specifier } end

header  ::

	lattice_dimensions { constraint_specifier }

	lattice_dimensions torus

lattice_dimensions ::

	dimensions x_dimension y_dimension z_dimension

constraint_specifier ::

	constrain constraint_selector

constraint_selector ::

	x0

	x1

	y0

	y1

	z0

	z1

body_specifier ::

	body body_index { cell_specifier }

cell_specifier ::

	x_coordinate y_coordinate z_coordinate

The use to the torus domain and constraints are mutually exclusive. The syntax may be more easily grasped by examining the example below.
