1.1.1.3 G2S

The G2S (two-dimensional geometry support library) was designed to provide geometry related functions. These functions include basic checks on geometries as well as manipulation functions to insert or delete geometry elements like points, lines, faces, boundaries, or segments. It defines functions to query topological information like the boundary of a segment, or the faces that share a line. By defining its own data representation and implementing its own interpolation mechanism (the so-called slab method [9]) it does not profit from the functions and data structures provided by the GRS module. Therefore, the grid lists in a PIF file are completely ignored. Inconsistencies that are eventually introduced by manipulating the geometry are not detected by either the GRS or the G2S module.
