Example VMesh structure for storing the geometry shows the use of VGeMesh for storing a geometry. Numbers within parentheses represent coordinate values. Numbers next to black dots represent node numbers. Numbers within brackets represent edge numbers. Numbers within curly braces represent boundary numbers.
Numbers delimited by asterisks are region numbers.
There are two regions and region one has two boundaries. PI , and PJ are used to store the coordinates of the spatial points not necessarily identical to their use in the Mesh VGroup. The Quads Vdata is an integer dataset containing ideces into the Coordinates Vdata for the points that define a quad, ordered as shown in section 2.4.2.3. There are thus four indeces for each quad. The Triangles Vdata is an intefer dataset that contains indeces into the connectivity Vdata of the Mesh structure.
