File-Contents (in Catchwords)

1. static informations:
   • number of polygons in the computational grid,
   • number of edges (with flow) in the computational grid,
   • number of subpolygons for plotting purposes,
   • number of subedges for plotting purposes, and
   • number of subvertices for plotting purposes.
2. dynamic data:

   • polygon data (for each polygon of the computational grid):

   • polygon number (informative),
   • number of subpolygons for plotting purposes within polygon, and
   • subpolygon data for plotting purposes (for all plot subpolygons of a polygon):

   • local (plot) subpolygon number (informative),
   • number of subvertices for plotting purposes within (plot) subpolygon,
   • pointer to subpolygon class of polygon (local class index for (computational) polygon), and
   • list of x- and y-coordinates for (plot) subpolygon.

   • edge data (for each edge with flow of the computational grid):

   • edge number (informative),
   • number of subedges for plotting purposes at edge, and
   • subedge data for plotting purposes (for all plot subedges of an edge):

   • local (plot) subedge number (informative),
   • pointer to subedge class of edge (local class index for (computational) edge), and
   • list of x- and y-coordinates for start and end point of (plot) subedge.
