HEX_MESH
Meshes of Hexagons in 2D

HEX_MESH is a data directory which contains examples of files that define a hexagonal mesh.

A hex mesh is a mesh of a 2D region based on hexagons. A hex mesh can be defined by using two files:

• the node file lists the coordinates of a set of points.
• the element file lists sets of 6 node indices, forming the elements.

Sample Files:

DRAGON is an irregular mesh of 14 hexagons.

• dragon_nodes.txt, the coordinates of nodes;
• dragon_elements.txt, the nodes that form the elements.
• dragon.png, a PNG image of the mesh created by MESH_DISPLAY.

STRIP is a mesh of 12 hexagons that roughly form a 3x4 strip.

• strip_nodes.txt, the coordinates of nodes;
• strip_elements.txt, the nodes that form the elements.
• strip.png, a PNG image of the mesh created by MESH_DISPLAY.
