Finite Difference Method (FDM)
un.uobasrah.edu.iq/lectures/13717.pdf
The finite difference approximation derivatives are one of the simplest and of the oldest methods to solve differential equation. It was already known by L .Euler (1707-1783)is one dimension of space and was probably extended to dimension two by C. Runge (1856-1927).
Finite difference method - Wikipedia
https://en.wikipedia.org/wiki/Finite_difference_method
In numerical analysis, finite-difference methods (FDM) are a class of numerical techniques for solving differential equations by approximating derivatives with finite differences. Both the spatial domain and time interval (if applicable) are discretized, or broken into a finite number of steps, and the value of the solution at these discrete points is approximated by solving algebraic equations contai…

Jul 22, 2013 · This module has been proved in the classroom for four consecutive years. It has brought several dozen students to develop their own 2D Navier-Stokes finite-difference solver from scratch in just over a month (with two class meetings per week). The module consists of the following steps (links are to the individual IPython Notebooks):

Finite difference - Wikipedia
https://en.wikipedia.org/wiki/Finite_difference
A finite difference is a mathematical expression of the form f (x + b) − f (x + a). If a finite difference is divided by b − a, one gets a difference quotient. The approximation of derivatives by finite differences plays a central role in finite difference methods for the numerical solution of differential equations, especially boundary value problems. Certain recurrence relationscan be written as difference equations by replacing iteration notatio…

3.5. FINITE DIFFERENCES AND FAST POISSON SOLVERS c 2006 Gilbert Strang The success of the method depends on the speed of steps 1 and 3. Step 2 is fast. To see that U in step 3 is correct, multiply it by the matrix K. Every eigenvector gives Ky = y. That cancels the in each denominator. The result is that KU agrees with the vector F in step 1.

The Finite-Difference Eigenmode (FDE) solver calculates the spatial profile and frequency dependence of modes by solving Maxwell's equations on a cross-sectional mesh of the waveguide. The solver calculates the mode field profiles, effective index, and loss. Integrated frequency sweep makes it easy to calculate group delay, dispersion, etc.
