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). Jun 09, 2013 | Comments 0 Advancements in personal computer technology have conveniently coincided with developments in numerical investigation towards increased complexity of computational algorithms based on finite variation approaches. Finite Difference Scheme for the Heat Equation. Mathematical models, typically a system of ordinary or partial differential equations, can provide considerable insight into the dynamics of biological systems. In both cases, Mathematica was faster (2 times faster in the later case). For initial investigations, it suffices to . The rate of convergence (or divergence) depends on the problem data and the inhomogeneous function . The spatial derivatives are approximated by finite differences, and the resulting set of ordinary differential equations is integrated over the 2-dimensional coronal domain using the second-order (in time) Heun's method with a fixed time step (0.1 day-1). 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. We apply a finite difference scheme to the heat equation, , and study its convergence.
