GREENLAND is a triangulation of Greenland, using a graded (varying-size) mesh of 33,343 nodes and 64,125 nodes. The resulting image is essentially a red blob the shape of Greenland. However, using the ZOOM tool, it is possible to see interesting details of the mesh.

• greenland.node, the nodes;
• greenland.ele, the elements;
• greenland_zoom.png, a zoomed image of the upper right margin of the triangulation.

SQUARE_CIRCLE_HOLE.1 is a square region with a circular hole. 826 nodes and 1517 elements are used.

• square_circle_hole.1.node, the nodes;
• square_circle_hole.1.ele, the elements;
• square_circle_hole.1.png, an image of the triangulation.
