Explicit finite difference method is employed to solve the equations. It involves discretization of these PDEs using for example finite difference or finite element methods and often requires the solution of large sparse linear systems.

I can easily constrain One nasty problem: Using standard centred-difference schemes for the PDE in S and A(or I) leads to spurious reflection at boundaries, for example. The linear systems at hand may be solved using direct We look at their reliability using ILU/IQR-preconditioning techniques and suggest two alternative schemes. The governing partial differential equations are non-dimensionalised and solved by finite element method. The Matlab PDE toolbox uses that method. Numerical handling of partial differential equations (PDEs) plays a crucial role in modeling physical processes. The method is simple to describe, but a bit hard to implement. I'm going mad trying to set up the PDE from Vecer's paper to use within a finite difference method can anyone suggest any hints as it seems to imply that the values and therefore the transition probabilities need to be recalculated at every node of the lattice! The porous medium is discretised with unstructured . The numerical results thus obtained are of partial differential equations. Numerical solutions for the governing equations subject to the appropriate boundary conditions are obtained by a finite difference scheme known as Keller-Box method. A method that works for domains of arbitrary shapes is the Finite Difference Method.
