I do not know for sure ofcourse, but that is the rumor. Advanced users can override these options, Consider the following PDE: We seek a solution, f(x,y) on the domain [0,10]x[0,10]. First, we will divide the domain into a grid. Emphasis will be on the implementation of numerical schemes to practical problems of the engineering and physical sciences. In both cases, Mathematica was faster (2 times faster in the later case). There are several different ways to approximate the solution to a PDE, just as there are several different ways to approximate the value of \(\pi\). Finite-difference time-domain methods still play an important role for many PDE applications. I did a matrix rank test some time ago, and I also did finite difference scheme for pde and a direct solver using sparse matrix. Using finite differences and the Crank-Nicholson implicit scheme for solving parabolic type partial differential equations, a computer program has been developed for solving the one-dimensional, vertical movement of water in soils. If you try to enter this elliptic PDE into NDSolve, Mathematica will vigorously protest. Instead, you can try to implement a finite difference method. NDSolve switches between integration schemes based on the problem at hand, adapting step sizes and monitoring stiffness as it goes.
