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]. In particular, they have been used to numerically integrate systems of partial differential equations (PDEs), which are time-dependent, and of hyperbolic type (implying wave-like solutions, with a finite propagation velocity). Numerical solutions for the governing equations subject to the appropriate boundary conditions are obtained by a finite difference scheme known as Keller-Box method. The porous medium is discretised with unstructured . NDSolve switches between integration schemes based on the problem at hand, adapting step sizes and monitoring stiffness as it goes. Instead, you can try to implement a finite difference method. I do not know for sure ofcourse, but that is the rumor. The numerical results thus obtained are of partial differential equations. First, we will divide the domain into a grid. If you try to enter this elliptic PDE into NDSolve, Mathematica will vigorously protest. Explicit finite difference method is employed to solve the equations. Two such methods, the In this thesis, the subtext is that such scattering-based methods can and should be treated as finite difference schemes, for purposes of analysis and comparison with standard differencing forms. The governing partial differential equations are non-dimensionalised and solved by finite element method.
