2008最近关于PDE数值求解的书籍 Partial differential equations arise in a number of physical problems, such as fluid flow, heat transfer, solid mechanics and biological processes. These equations often fall into one of three types. Hyperbolic equations are most commonly associated with advection, and parabolic equations are most commonly associated with diffusion. Elliptic equations are most commonly associated with steady-states of either parabolic or hyperbolic problems.
