The files for the mesh are expected to have the following specified relation to the input file <FILE> e.g. for the input file example.cig it is searched for:

example_Coord.dat	File with coordinates of the mesh vertices.
example_Elms.dat	File with information of the mesh cells.
example_Attr.dat	File with cell, edge and vertex attributes.
example_EdgRadia.dat	File with radia of circular edges.
example_EdgCorr.dat	File with information about periodic edges.

Furthermore, semi-infinite rectangles can be defined via the file for the input parameter.

Type	Name (default value)	Stands for		Compulsory
string array	InfiniteQuad (empty)	Array of semi-infinite rectangles, e.g. string array InfiniteQuad { 1 "2 1 4", 2 "104 103 4" }		No
