Notes:
DIMACS10 set: numerical/NACA0015 source: http://www.cc.gatech.edu/dimacs10/archive/numerical.shtml 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.
