This paper presents an implementation of the finite-difference time-domain (FD-TD) method in Java using CPML boundary conditions. The FD-TD code was validated with a canonical problem. The performance ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

In the two-dimensional (2D) case and 5-point stencil, the Complete Centered Finite Difference Method presents a dispersion relation equivalent to Galerkin/Least-Squares Finite Element Method. In the ...

This repository contains a Python implementation of numerical differentiation using Forward, Backward, and Centered methods with nth order derivatives. The code allows users to select the ...

A non-standard fitted operator finite difference method based on the Crank-Nicolson discretization for time variable comprising a non-standard fitted operator finite difference on uniform mesh for ...
