This VGRID/USM3D computation was performed at the request of the National Air & Space Museum and in cooperation with the Boeing Commercial Aircraft Company. The above image has been enlarged to over 20 feet for use as a wall mural in the "How Things Fly" gallery which opened September 19, 1996.
As a side benefit to NASA and Boeing, comparisons of the USM3D solution, which includes a coupled Interactive Boundary Layer (IBL) code to model viscous effects, are underway with Boeing flight data. The flow conditions are Mach = 0.82, angle of attack = 1.94 deg., and Reynolds number = 55 Million.
The background for the surface pressure contour image shown below illustrates the nature of the unstructured tetrahedral grid. The tetrahedral cells are clustered near the aircraft, and grow in size away from the body.
