The instances NACA0015, M6, 333SP, AS365, and NLR are 2-dimensional FE
triangular meshes with coordinate information. 333SP and AS365 are    
actually converted from existing 3-dimensional models to 2D places,   
while the rest are created from geometry. The corresponding coordinate
files have been assembled in one archive. They have been created and  
contributed by Chan Siew Yin with the help of Jian Tao Zhang,         
Department of Mechanical Engineering, University of New Brunswick,    
Fredericton, Canada.
