Derivative Convergence ( Frames from the Movie )
The following frames depict the derivative of ``density'' at every
element in the flow field with respect to ``angle of attack'' for a
NACA 0012 Airfoil at ALPHA = 2.0, REY = 9.E6, and FSMACH = 0.6. This
is a shock-free testcase. For this example, we were able to get good
agreement between derivatives computed by BB, IIM, and one-sided
finite differences on the SP2.
