    DIMACS10 set: numerical/333SP                                         
    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.
