Questions tagged [pde]

Use this tag for questions about partial differential equations. For questions about the Eclipse Plugin Development Environment, use eclipse-pde instead.

Partial Differential Equations are differential equations that contain unknown multivariable functions and their partial derivatives. See [http://en.wikipedia.org/wiki/Partial_differential_equation][1]

The Eclipse Plug-in Development Environment (PDE) provides tools to create, develop, test, debug, build and deploy Eclipse plug-ins, fragments, features, update sites and RCP products. PDE also provides comprehensive OSGi tooling. See [http://www.eclipse.org/pde/][2]

Questions about the Eclipse Plug-in Development Environment are better tagged as 'eclipse-pde'.

Matrix to generate finite difference

I'm implementing a finite difference scheme for a 2D PDE problem. I wish to avoid using a loop to generate the finite differences. For instance to generate a 2nd order central difference of u(x,y)_xx, I can multiply u(x,y) by the following: Is…

Efficiently computing the 3D Laplacian using FFT and Python

For solving a PDE (Schrödinger equation), I need to compute the Laplace operator in three dimensions. My current solution is this (part of the code which requires by far the most time): for n in range(Ntstep): # loop for i in…
