This classi cation re ects the fact that several basic features of the qualitative behaviour of solutions, including the well-posedness of corresponding boundary- and/or initial-value Dear Robert, I were referring only to the internal nodes of each surface, in order to give a trace about how things work. You have to do the same thing also for the nodes of each edge (without The boundary layer equations are solved by numerical methods. According to the standard theory, the pressure is known (from the solution of inviscid equations as mentioned above). The boundary layer equations form a system of parabolic equations. The mathematical nature of this system is similar to the heat equation. Multiple Choice :a.
