Trigulated Friction analysis based on actual wetted areas
Mach Number = 1.4
Altitude = 30000 feet
Cd due to friction = 1.813 with Reference Area = 1 Sq. ft

When run through Triwave, the program crashes. Possible cause could be a bug in Triwave, Trisurf or GTS itself. The triangulated output above has Self-intersecting triangles. Refer to the GTS manual for the definition of Self-intersecting surfaces.
