258 Chapter 12 Compressible Flow Analysis

Since the ANSYS files can be downloaded from the
book website, users can exercise more on this problem. Users may
change the flow Mach number and angle of attack to obtain
different flow solutions. Such practice provides good experience to
realize that solving compressible flows always requires consider-
able effort. The effort is from the fact that the governing differen-
tial equations are strongly coupled and nonlinear. A large number
of small cells are thus needed to provide accurate flow solutions. A
large amount of small cells requires excessive computational time
and computer memory.
