This section provides links to numerical tools for gravitational lensing.
1. The Astro-Code Wiki: www.astrosim.net/code
The Astro-Code Wiki is a growing on-line repository of software and software tests for state of the art simulation, modelling and analysis in astrophysics. There are already two sections on gravitational lens software:
(i) Lensing software: www.astrosim.net/code/doku.php; and
(ii) Reconstruction tests for lensing software: www.astrosim.net/code/doku.php
These may be added to or edited by applying for an account on the main page.
2. The SimpLens Java Applet: www.physik.uzh.ch/~psaha/astron/lens/simplens.php
A program for illustrating some of the theoretical ideas important in gravitational lensing in an interactive way.
